Summary:
This patch adds a very basic `FILE` type and basic `fwrite`.

It also removes `snprintf` from `StdIO`'s function spec because `VarArgType` was causing the generation to fail.

Fix MLIR test case failure introduced by
89e0662d. LLVM's IR builder
now automatically sets the alignment on alloca.

This makes no impact on the test cases because affine-data-copy-generate
runs whole function canonicalization at its end; however, the latter
will be removed in a pending revision. It is thus useful to clean up
these affine.applys right here, and eventually, not even generate
these (when the right API to compose by construction is in place).

Still not great and we could probably codegen this better, but
11 was clearly ridiculous.

[X86] Split AVX512 getCastInstrCost into tables that require useAVX512Regs() and those that just operate on 256 or smaller vectors.

Use useAVX512Regs() to skip lookups instead of using type legalization
action.

[X86] Add truncate cost model tests to min-legal-vector-width.ll for when we're avoiding 512 bit vectors.

Update local test object "in place" from remote test object.  We need to
do this to ensure that discovered test object which is used for printing
test results reflect the changes.

> Why are we sending back the whole test object from the worker process
> (lit.worker.execute) instead of just the result?

Unfortunately, the test result is not the only "result" of test
execution.  Other members (e.g., xfails, requires) of the Test class are
set only during execution.  Those members affect the behavior of
`isExpectedToFail` and `setResult`, and are accessed when printing
results.  For example, xunit.xml test results include missing features
for "skip reasons".  The lack of separation between an immutable "test
definition" and "generated outputs" (including the primary result and
other secondary state) is unfortunate historical design decision in lit.

> Why do we update the initial test object instead of just discarding it
> and continuing with the pickled test object?

Both of these approaches would work.  However, note that we need a fully
populated test object for printing results.  Updating the existing one
seems to be the easier path.

This was assuming a scalarizing unmerge, and would fail assert if the
unmerge was to smaller vector types.

Building 'espresso' from llvm-test-suite revealed missing support

Ports the existing DAG combines, minus the simplify demanded bits
which seems to have no equivalent now. Without these, this isn't
particularly helpful in most of the IR sample cases.

Move ModuleSummaryAnalysis from libAnalysis to libObject to break the dependency from Analysis to Object

ModuleSummaryAnalysis is the only file in libAnalysis that brings a
dependency on the CodeGen layer from libAnalysis, moving it breaks this
dependency.

Summary:
In CFGStackify, `fixUnwindMismatches` function fixes unwind destination
mismatches created by `try` marker placement. For example,
```
try
  ...
  call @qux  ;; This should throw to the caller!
catch
  ...
end
```
When `call @qux` is supposed to throw to the caller, it is possible that
it is wrapped inside a `catch` so in case it throws it ends up unwinding
there incorrectly. (Also it is possible `call @qux` is supposed to
unwind to another `catch` within the same function.)

To fix this, we wrap this inner `call @qux` with a nested
`try`-`catch`-`end` sequence, and within the nested `catch` body, branch
to the right destination:
```
block $l0
  try
    ...
    try                 ;; new nested try
      call @qux
    catch               ;; new nested catch
      local.set n       ;; store exnref to a local
      br $l0
    end
  catch
    ...
  end
end
local.get n             ;; retrieve exnref back
rethrow                 ;; rethrow to the caller
```

The previous algorithm placed the nested `try` right before the `call`.
But it is possible that there are stackified instructions before the
call from which the call takes arguments.
```
try
  ...
  i32.const 5
  call @qux  ;; This should throw to the caller!
catch
  ...
end
```

In this case we have to place `try` before those stackified
instructions.
```
block $l0
  try
    ...
    try                 ;; this should go *before* 'i32.const 5'
      i32.const 5
      call @qux
    catch
      local.set n
      br $l0
    end
  catch
    ...
  end
end
local.get n
rethrow
```

We correctly handle this in the first normal `try` placement phase
(`placeTryMarker` function), but failed to handle this in this
`fixUnwindMismatches`.

The new format should be equivalent to the old format, and it is now the
default format when running the libc++ and libc++abi tests. This commit
changes the libunwind tests to use the new format by default too. If
unexpected failures are discovered, it should be fine to revert this
commit until they are addressed.

Also note that it is still possible to use the old format by passing
`--param=use_old_format=True` when running Lit for the time being.

The libc++ test suite currently defines several features that are not
used anywhere in the tests, or that are redundant with other features.
For the purpose of simplifying config.py and to ease the bring up of a
new configuration, this commit removes some of these features:

- rename dylib-has-no-filesystem to c++filesystem-disabled, which exists
- rename apple-darwin to just darwin, which is already set
- remove useless setting of libstdc++, which is already set correctly
- remove libcpp-abi-unstable, which is not used anywhere
- remove the glibc-XXX features, which are not used anywhere

I broke bots last week and tried a few things to fix them.
