Since `raw_string_ostream` doesn't own the string buffer, it is
desirable (in terms of memory safety) for users to directly reference
the string buffer rather than use `raw_string_ostream::str()`.
Work towards TODO comment to remove `raw_string_ostream::str()`.

For some reason this was missing from STLExtras.

FileCheck currently compiles a regular expression of the form
`Prefix1|Prefix2|...` and uses it to find the next prefix in the input.
If we had a fast regex implementation, this would be a useful thing to
do, as the regex implementation would be able to match multiple prefixes
more efficiently than a naive approach. However, with our actual regex
implementation, finding the prefixes basically becomes O(InputLen *
RegexLen * LargeConstantFactor), which is a lot worse than a simple
string search.
Replace the regex with StringRef::find(), and keeping track of the next
position of each prefix. There are various ways this could be improved
on, but it's already significantly faster that the previous approach.
For me, this improves check-llvm time from 138.5s to 132.5s, so by
around 4-5%.
For vector-interleaved-load-i16-stride-7.ll in particular, test time
drops from 5s to 2.5s.

Since 65b13610a5226b84889b923bae884ba395ad084d, raw_string_ostream has
been unbuffered by default. Based on an audit of llvm/utils/, this
commit removes every call to `raw_string_ostream::flush()` and any call
to `raw_string_ostream::str()` whose result is ignored or that doesn't
help with clarity.
I left behind a few calls to `str()`. In these cases, the underlying
std::string was declared pretty far away and never used again, whereas
stream recently had its last write. The code is easier to read as-is;
the no-op call to `flush()` inside `str()` isn't harmful, and when
https://reviews.llvm.org/D115421 lands it'll be gone anyway.

For example,
<https://lab.llvm.org/buildbot/#/builders/132/builds/3929>
has this diagnostic:
```
/opt/gcc/9.3.0/snos/include/g++/bits/stl_tree.h:780:8: error: static assertion failed: comparison object must be invocable as const
780 | is_invocable_v<const _Compare&, const _Key&, const _Key&>,

In input dump annotations, `check:2'1` indicates diagnostic 1 for the
`CHECK` directive on check file line 2. Without this patch,
`-dump-input` computes the diagnostic index with the assumption that
FileCheck *consecutively* produces all diagnostics for the same
pattern. Already, that can be a false assumption, as in the examples
below. Moreover, it seems like a brittle assumption as FileCheck
evolves. Finally, it actually complicates the implementation even if
it makes it slightly more efficient.
This patch avoids that assumption. Examples below show results after
applying this patch. Before applying this patch, `'N` is omitted
throughout these examples because the implementation doesn't notice
there's more than one diagnostic per pattern.
First, `CHECK-LABEL` violates the assumption because `CHECK-LABEL`
tries to match twice, and other directives can match in between:
```
$ cat check
CHECK: foobar
CHECK-LABEL: foobar
$ FileCheck -vv check < input |& tail -8
<<<<<<
1: text
2: foobar
label:2'0 ^~~~~~
check:1 ^~~~~~
label:2'1 X error: no match found
3: text
>>>>>>
```
Second, `--implicit-check-not` is obviously processed many times among
other directives:
```
$ cat check
CHECK: foo
CHECK: foo
$ FileCheck -vv -dump-input=always -implicit-check-not=foo \
check < input |& tail -16
<<<<<<
1: text
not:imp1'0 X~~~~
2: foo
check:1 ^~~
not:imp1'1 X
3: text
not:imp1'1 ~~~~~
4: foo
check:2 ^~~
not:imp1'2 X
5: text

A more general name might be match-time error propagation. That is,
it's conceivable we'll one day have non-numeric errors that require
the handling fixed by this patch.
Without this patch, FileCheck behaves as follows:
```
$ cat check
CHECK-NOT: [[#0x8000000000000000+0x8000000000000000]]
$ FileCheck -vv -dump-input=never check < input
check:1:54: remark: implicit EOF: expected string found in input
CHECK-NOT: [[#0x8000000000000000+0x8000000000000000]]
^
<stdin>:2:1: note: found here
^
check:1:15: error: unable to substitute variable or numeric expression: overflow error
CHECK-NOT: [[#0x8000000000000000+0x8000000000000000]]
^
$ echo $?
0
```
Notice that the exit status is 0 even though there's an error.
Moreover, FileCheck doesn't print the error diagnostic unless both
`-dump-input=never` and `-vv` are specified.
The same problem occurs when `CHECK-NOT` does have a match but a
capture fails due to overflow: exit status is 0, and no diagnostic is
printed unless both `-dump-input=never` and `-vv` are specified. The
usefulness of capturing from `CHECK-NOT` is questionable, but this
case should certainly produce an error.
With this patch, FileCheck always includes the error diagnostic and
has non-zero exit status for the above examples. It's conceivable
that this change will cause some existing tests to fail, but my
assumption is that they should fail. Moreover, with nearly every
project enabled, this patch didn't produce additional `check-all`
failures for me.
This patch also extends input dumps to include such numeric error
diagnostics for both expected and excluded patterns.
As noted in fixmes in some of the tests added by this patch, this
patch worsens an existing issue with redundant diagnostics. I'll fix
that bug in a subsequent patch.

When commit da108b4ed4e6e7267701e76d5fd3b87609c9ab77 introduced
the CHECK-NEXT directive, it added logic to skip to the next line when
printing a diagnostic if the current matching position is at the end of
a line. This was fine while FileCheck did not support regular expression
but since it does now it can be confusing when the pattern to match
starts with the expectation of a newline (e.g. CHECK-NEXT: {{\n}}foo).
It is also inconsistent with the column information in the diagnostic
which does point to the end of line.
This commit removes this logic altogether, such that failure to match
diagnostic for such cases would show the end of line and be consistent
with the column information. The commit also adapts all existing
testcases accordingly.
Note to reviewers: An alternative approach would be to restrict the code
to only skip to the next line if the first character of the pattern is
known not to match a whitespace-like character. This would respect the
original intent but keep the inconsistency in terms of column info and
requires more code. I've only chosen this current approach by laziness
and would be happy to restrict the logic instead.

Substitutions are already reported in the diagnostics appearing before
the input dump in the case of failed directives, and they're reported
in traces (produced by `-vv -dump-input=never`) in the case of
successful directives. However, those reports are not always
convenient to view while investigating the input dump, so this patch
adds the substitution report to the input dump too. For example:
```
$ cat check
CHECK: hello [[WHAT:[a-z]+]]
CHECK: [[VERB]] [[WHAT]]
$ FileCheck -vv -DVERB=goodbye check < input |& tail -8
<<<<<<
1: hello world
check:1 ^~~~~~~~~~~
2: goodbye word
check:2'0 X~~~~~~~~~~~ error: no match found
check:2'1 with "VERB" equal to "goodbye"
check:2'2 with "WHAT" equal to "world"
>>>>>>
```
Without this patch, the location reported for a substitution for a
directive match is the directive's full match range. This location is
misleading as it implies the substitution itself matches that range.
This patch changes the reported location to just the match range start
to suggest the substitution is known at the start of the match. (As
in the above example, input dumps don't mark any range for
substitutions. The location info in that case simply identifies the
right line for the annotation.)

`FILECHECK_OPTS` was implemented so that a test runner, such as CI,
can specify FileCheck debugging options, such as `-v` and `-vv`.
However, if a test suite has a FileCheck call that already specifies
`-v` or `-vv`, then that call will fail if `FILECHECK_OPTS` also
specifies it.
For `-vv`, this problem already exists:
`clang/test/CodeGen/aarch64-v8.2a-fp16-intrinsics-constrained.c`
It's not yet clear if the `-vv` in that test was intentional, but this
usage shouldn't fail anyway. It's already true that FileCheck permits
`-vv` and `-v` together even though `-vv` implies `-v`.
Compare D70784, which fixed the same problem for `-dump-input`.

Sometimes you want to disable a FileCheck directive without removing
it entirely, or you want to write comments that mention a directive by
name. The `COM:` directive makes it easy to do this. For example,
you might have:
```
; X32: pinsrd_1:
; X32: pinsrd $1, 4(%esp), %xmm0
; COM: FIXME: X64 isn't working correctly yet for this part of codegen, but
; COM: X64 will have something similar to X32:
; COM:
; COM: X64: pinsrd_1:
; COM: X64: pinsrd $1, %edi, %xmm0
```
Without this patch, you need to use some combination of rewording and
directive syntax mangling to prevent FileCheck from recognizing the
commented occurrences of `X32:` and `X64:` above as directives.
Moreover, FileCheck diagnostics have been proposed that might complain
about the occurrences of `X64` that don't have the trailing `:`
because they look like directive typos:
<http://lists.llvm.org/pipermail/llvm-dev/2020-April/140610.html>
I think dodging all these problems can prove tedious for test authors,
and directive syntax mangling already makes the purpose of existing
test code unclear. `COM:` can avoid all these problems.
This patch also updates the small set of existing tests that define
`COM` as a check prefix:
- clang/test/CodeGen/default-address-space.c
- clang/test/CodeGenOpenCL/addr-space-struct-arg.cl

Without this patch, `--dump-input` annotations on a single input line
are sorted by the associated directive's check-file line. That seemed
fine because that's often identical to the order in which FileCheck
looks for matches for those directives.
The first problem is that an `--implicit-check-not` pattern has no
check-file line. The logical equivalent is sorting in command-line
order, but that's not implemented.
The second problem is that, unlike a directive, an
`--implicit-check-not` pattern applies at many points, between many
different pairs of directives. However, sorting in command-line order
gathers all its associated diagnostics together at one point in an
input line's list of annotations.
In general, it seems to be easier to understand FileCheck's logic when
annotations on a single input line are sorted in the order FileCheck
produced the associated diagnostics, so this patch makes that change.
As documented in the patch, the annotation sort order is also
especially relevant to `CHECK-LABEL`, `CHECK-NOT`, and `CHECK-DAG`, so
this patch updates or extends tests to check the sort makes sense for
them. (However, the sort for `CHECK-DAG` annotations should not
actually be altered by this patch.)

Problem: `FILECHECK_OPTS` was implemented so that a test runner, such
as a bot, can specify FileCheck debugging options, such as
`-dump-input=fail`. However, some existing test suites have FileCheck
calls that already specify `-dump-input=fail` or `-dump-input=always`.
Without this patch, such tests fail under such a test runner because
FileCheck doesn't accept multiple occurrences of `-dump-input`.
Solution: This patch permits multiple occurrences of `-dump-input` by
assigning precedence to its values in the following descending order:
`help`, `always`, `fail`, and `never`. That is, any occurrence of
`help` always obtains help, and otherwise the behavior is similar to
`-v` vs. `-vv` in that the option specifying the greatest verbosity
has precedence.
Rationale: My justification for the new behavior is as follows. I
have not experienced use cases where, either as a test runner or as a
test author, I want to **limit** the permitted debugging verbosity
(except as a test author in FileCheck's or lit's test suites where the
FileCheck debugging output itself is under test, but the solution
there is `env FILECHECK_OPTS=`, and I imagine we should use the same
solution anywhere else this need might occur). Of course, as either a
test runner or test author, it is useful to **increase** debugging
verbosity.
