This patch makes `Relocation::Addend` to be `ELFYAML::YAMLIntUInt` and not `int64_t`.

`ELFYAML::YAMLIntUInt` it is a new type and it has the following benefits/features:

1) For an 64-bit object any hex/decimal addends
   in the range [INT64_MIN, UINT64_MAX] is accepted.
2) For an 32-bit object any hex/decimal addends
   in range [INT32_MIN, UINT32_MAX] is accepted.
3) Negative hex numbers like -0xffffffff are not accepted.
4) It is printed as decimal. I.e. obj2yaml will print
   something like "Addend: 125", this matches the current behavior.

This fixes all FIXMEs in `relocation-addend.yaml`.

Summary:
Adds the constraints described below to ensure that we
can tie variables of SVE ACLE types to operands in inline-asm:
 - y: SVE registers Z0-Z7
 - Upl: One of the low eight SVE predicate registers (P0-P7)
 - Upa: Full range of SVE predicate registers (P0-P15)

This is a follow-up for D75608.
The `Offset` property is unused and can be removed to reduce tests.

This patch does nothing with `reloc-types-elf-i386.test` which has a different
structure and kind of tests the `Offset`. I think we might want to split it probably.

Currently, when building with the Unix support library and `isatty` does
not exist for the target platform (i.e. `HAVE_ISATTY` is false),
compilation of the file `raw_ostream.cpp` will fail due to direct use of
`isatty` in the function `raw_fd_ostream::preferred_buffer_size()`.

Use is_displayed() to fix the problem.

This fails an assert because the type is marked in the calling
convention td file as needing promotion, but the code doesn't know
how to do it.

It also much more complicated because we try to pass these in
xmm/ymm/zmm registers. As of a few weeks ago we do this promotion
from getRegisterTypeForCallingConv before the td file generated
code gets involved.

which is the more appropriate API for its use-case.

This test fails on ppc which was unintended.

Revision: D73674.

Summary: PatternState was a mechanism to pass state between the match and rewrite calls of a RewritePattern. With the rise of matchAndRewrite, this class is unused and unnecessary. This revision removes PatternState and simplifies PatternMatchResult to just be a LogicalResult. A future revision will replace all usages of PatternMatchResult/matchSuccess/matchFailure with LogicalResult equivalents.

Fixes -Werror builds.

Note that I'm not asserting this code is correct; I'm simply adding coverage for what's there already.  I'm reasonable sure the logic works for existing relaxable instructions, but I wouldn't be suprised if there were incorrect cases for other instructions.  (i.e. is it legal to add prefixes to all instructions?)

- libclang_rt.profile should be added when -fcs-profile-generate is on thecommand line.
- OPT_fno_profile_instr_generate was used as a negative for OPT_fprofile_generate. Fix it to use OPT_fno_profile_generate.

[Concepts] Fix incorrect control flow when TryAnnotateTypeConstraint annotates an invalid template-id

TryAnnotateTypeConstraint could annotate a template-id which doesn't end up being a type-constraint,
in which case control flow would incorrectly flow into ParseImplicitInt.

Reenter the loop in this case.
Enable relevant tests for C++20. This required disabling typo-correction during TryAnnotateTypeConstraint
and changing a test case which is broken due to a separate bug (will be reported and handled separately).

Summary:
Run StackSafetyAnalysis at the end of the IR pipeline and annotate
proven safe allocas with !stack-safe metadata. Do not instrument such
allocas in the AArch64StackTagging pass.

This is the second patch in a series of patches to enable basic block
sections support.

This patch adds support for:

* Creating direct jumps at the end of basic blocks that have fall
through instructions.
* New pass, bbsections-prepare, that analyzes placement of basic blocks
in sections.
* Actual placing of a basic block in a unique section with special
handling of exception handling blocks.
* Supports placing a subset of basic blocks in a unique section.
* Support for MIR serialization and deserialization with basic block
sections.
