[MLIR][OpenMP] Fix mapper being attached to partial maps. (#178247)
Fix OpenMP mapper lowering by attaching user-defined/default mappers
only to the base parent entry, not combined/segment entries. This
prevents mapper calls with partial sizes. Added relevant tests.
[flang] Remove `AmbiguousStructureConstructor` warnings (#178088)
Remove `AmbiguousStructureConstructor` warnings. This removes harmless
warnings about standards-conforming generic function references that
are never ambiguous with structure constructors.
[MLIR][Python] Remove partial LLVM APIs in python bindings (#178290)
mlir-py bindings should only rely on C mlir APIs.
This PR replaced partial LLVM utilities (`Twine`, `ArrayRef`,
`SmallVector`, `StringRef`) with equivalent STL, and added a `join()`
helper function in `IRCore.cpp` to concat strings.

[CSSPGO] Preserve pseudo-probe discriminators in cloneWithBaseDiscriminator (#178267)
In the O0 pipeline, `SampleProfileProbePass` runs before
`AddDiscriminatorsPass`. The
pseudo-probe pass stores probe IDs in the discriminator field using a
special encoding
(bits [2:0] = 0x7 as marker). When `AddDiscriminatorsPass` later
processes instructions
on the same source line, it calls `cloneWithBaseDiscriminator()` which
overwrites these
pseudo-probe discriminators with DWARF base discriminators, breaking
sample profile
matching.
This patch adds a check to `cloneWithBaseDiscriminator()` to detect and
preserve
pseudo-probe discriminators, similar to the existing check in
`cloneByMultiplyingDuplicationFactor()`.

[clangd] Unify IndexAction callbacks into one (#178132)
This allows users of IndexAction who create the action but do not call
it (e.g. the call will happen through ToolExecutor) to do some work when
the action is complete, without assuming that a particular one of the
individual callbacks (e.g. include graph) will be called last.
[flang] Document experimental support for multi-image features (#178011)
This PR updates flang's Fortran standard conformance documentation to
reflect the recent addition of experimental support for multi-image
features.

[LifetimeSafety] Track transparent member functions for "all" GSL pointers (#177660)
Track transparent member functions (like data, begin, end, operator*,
etc) for all gsl::Pointer types and not just for STL types. This is a
change in semantics of `gsl::Pointer` annotations which now handles
specially **named** functions differently.
1. Tracking more methods that return pointers or references to objects
owned by the implicit object argument
2. Ensuring that methods like `data()`, dereference operators, and
begin/end iterators are properly tracked
The changes allow the analyzer to detect more cases where addresses of
stack memory are returned, particularly when working with GSL pointer
types that provide access to their underlying objects through methods
like `data()` or operators like `*` and `->`.
One particular idiom that is now detected is iterators involved in
range-based for-loops.

[DAGISel][NFC] Add XForm/Convert/CopyToReg Comments (#178379)
Thus updates the TableGen comments (both in the TableGen source, and the
code that TableGen produces) to make it clearer what is being
represented by the ConvertToTarget emitter, the XForm emitter, and the
CopyToReg emitter.
[InstCombine][profcheck] Add unknown branch weight to all selects in InstCombineMulDivRem.cpp (#178308)
These select instructions originate from code without existing branches,
so there's no existing branch weight data. Therefore, we add unknown
branch weights to all of them.
Tracking issue: #147390
[lldb-dap] Improve test performance by removing negative assertions. (#178041)
Investigating some of the biggest slow downs during tests, the biggest
offender is 'wait_for_stopped' requiring a negative assertion around the
'stopped' event.
It currently waits for a negative predicate to fail before continuing.
This means it must wait for the full DEFAULT_TIMEOUT (50s) before the
test is allowed to continue.
To mitigate this, I added a new `collect_events` helper that will wait
for the given event to occur with the DEFAULT_TIMEOUT, then wait for a
quiet period (0.25s) before returning.
This greatly reduces the amount of idle waiting during tests.
Additionally, looking a the performance of individual test files,
`TestDAP_launch` is the slowest overall test. No individual test is that
slow, but the fact it has so many tests in the same file results in the

cpucontrol: Be more strict with input validation
Avoid truncating 32-bit values. This would have saved me a bit of time
when I was looking at a cpuid leaf on my system and typed 0x80000001f
instead of 0x8000001f.

[DTLTO] support distributing bitcode from FatLTO objects (#176928)
We already have code to extract bitcode files from archives so they can
be distributed. Extend this code to extract bitcode from FatLTO objects
too, which otherwise cannot be used with DTLTO.
[flang-rt] Fix defining `pid_t` on GPU builds (#178470)
Summary:
We support building flang-rt on GPU targets. These do not have POSIX
types so we should not include this if it's not present.
