  [flang] Adding support of -fcoarray flang and init PRIF (#151675)

In relation to the approval and merge of the
[PRIF](https://github.com/llvm/llvm-project/pull/76088) specification
about multi-image features in Flang, here is a first PR to add support
for the `-fcoarray` compilation flag and the initialization of the PRIF
environment.
Other PRs will follow for adding support of lowering to PRIF.

  [DirectX][objdump] Add support for printing signatures (#153320)

This adds support for printing the signature sections as part of the
`-p` flag for printing private headers.

The formatting aims to roughly match the formatting used by DXC's
`/dumpbin` flag.

The original version's printed output left some trailing whitespace on
lines, which caused the tests to fail with the strict whitespace
matching.

Re-lands #152531.
Resolves #152380.

  Frontend: Define __SANITIZE_*__ macros for certain sanitizers.

Per discussion with @ojhunt and @AaronBallman we are moving towards
predefined macros and away from __has_feature and __has_extension
for detecting sanitizers and other similar features. The rationale
is that __has_feature is only really meant for standardized features
(see the comment at the top of clang/include/clang/Basic/Features.def),
and __has_extension has the issues discovered as part of #153104.

Let's start by defining macros for ASan, HWASan and TSan, consistently
with gcc.

  [msan] Reland with even more improvement: Improve packed multiply-add instrumentation (#153353)

This reverts commit cf002847a464c004a57ca4777251b1aafc33d958 i.e.,
relands ba603b5e4d44f1a25207a2a00196471d2ba93424. It was reverted
because it was subtly wrong: multiplying an uninitialized zero should
not result in an initialized zero.

This reland fixes the issue by using instrumentation analogous to
visitAnd (bitwise AND of an initialized zero and an uninitialized value
results in an initialized value). Additionally, this reland expands a
test case; fixes the commit message; and optimizes the change to avoid
the need for horizontalReduce.

The current instrumentation has false positives: it does not take into
account that multiplying an initialized zero value with an uninitialized
value results in an initialized zero value This change fixes the issue
during the multiplication step. The horizontal add step is modeled using
bitwise OR.

Future work can apply this improved handler to the AVX512 equivalent
intrinsics (x86_avx512_pmaddw_d_512, x86_avx512_pmaddubs_w_512.) and AVX
VNNI intrinsics.

This simply updates the pass's cognizance of these instructions, and for
the
most part the hazards where they might be encountered do not exist for
gfx12.
Nonetheless, encountering them has to be checked for as doing so would
indicate
a compiler error.
