  [InstCombine] Fold shuffles through all trivially vectorizable intrinsics (#141979)

This addresses a TODO in foldShuffledIntrinsicOperands to use
isTriviallyVectorizable instead of a hardcoded list of intrinsics, which
in turn allows more intriniscs to be scalarized by VectorCombine.

>From what I can tell every intrinsic here should be speculatable so an
assertion was added.

Because this enables intrinsics like abs which have a scalar operand, we
need to also check isVectorIntrinsicWithScalarOpAtArg.

  Fix/reapply "[libc] Migrate stdio tests to ErrnoCheckingTest." (#143972)

This reverts commit a93e55e57ed00a55f822c64e3520c7c732b58480 and fixes
build and test failures:

* Proper include added to setvbuf_test.cpp
* fgetc/fgetc_unlocked/fgets tests are ported to ErrnoSetterMatcher and
are made more precise. This fixes inconsistencies between expectations
in regular and GPU builds - ErrnoSetterMatcher is configured to omit
errno matching on GPUs, as fgetc implementation on GPU doesn't set
errno, in contrast to Linux.

  [bazel] Update llvm-config.h and disable DebugLoc tracking (#144125)

In c588224ca797886064a7a79f6c0114a6963c325e, @chapuni set
LLVM_ENABLE_DEBUGLOC_COVERAGE_TRACKING to 1, but from what I can tell,
this is not the default setting for CMake builds. I think the intention
was mostly just to update llvm-config.h to fix the Bazel build.

I'm adding LLVM_ENABLE_DEBUGLOC_ORIGIN_TRACKING as well to fix the build
for the same purpose.

  [libc][NFC] clean internal fd handling (#143991)

The previous internal fcntl implementation modified errno directly, this
patch fixes that. This patch also moves open and close into OSUtil since
they are used in multiple places. There are more places that need
similar cleanup but only got comments in this patch to keep it
relatively reviewable.

  [clang-scan-deps] Implement P2223R2 for DependencyDirectiveScanner.cpp (#143950)

P2223R2 allows the line-continuation slash `\` to be followed by
additional whitespace. The Clang lexer already follows this behavior,
also for versions prior to C++23. The dependency directive scanner
however only implements it for `#define` directives (15d5f5d).

This fully implements P2223R2 for the dependency directive scanner (for
any C++ standard) and aligns the dependency directive scanner's splicing
behavior with that of the Clang lexer.

For example, the following code was previously not scanned correctly by
`clang-scan-deps` but now works as expected:

```cpp
import \<whitespace here>
A;
```

The printf parser uses errno for setting up the %m conversion. It was

patch adds a direct dependency to fix it.
