[OpenMP][offload] Cross-team reductions with variable number of teams (#195102)
This is a part of a series of patches that rework OpenMP cross-team
reductions.
This patch changes the cross-team reduction runtime to no longer work
through larger number of teams in chunks. Instead, we allocate a
suitable-sized global buffer for the team values and let all teams run
at once. The last team that finishes uses a strided loop to reduce the
team values from the global buffer.
We also use `mapping::getNumberOfThreadsInBlock()` instead of
`omp_get_num_threads()` because the reduction of the team values runs
outside of the parallel region device code, which would make
`omp_get_num_threads()` always return 1. For Generic-SPMD mode, we also
want to use all available threads, which means that we need to copy the
reduction data from LDS (where it lives in that mode by default) to
scratch in codegen before calling the cross-team reduction.

[DirectX] Handle llvm.dx.resource.getbasepointer intrinsic in DXILResourceAccess pass (#204732)
The `llvm.dx.resource.getbasepointer` intrinsic is emitted for
`Constantbuffer<T>` element access and needs to be translated to
`llvm.dx.resource.load.cbufferrow` calls in the `DXILResourceAccess`
pass. The handling is identical to `llvm.dx.resource.getpointer` with a
0 offset.
Fixes #204234

file: normalize .result files to ensure trailing newline on install
Some upstream result files introduced in file 5.47 (e.g., bgcode.result)
lack a trailing newline, causing the contrib_file_tests ATF test to
fail with "cmp: EOF on bgcode.result". Generate normalized copies
of the expected results and install those instead.

[LifetimeSafety] Allow configuring lifetimebound fix-it spelling (#204045)
When suggesting `[[clang::lifetimebound]]` fix-its, allow users to
provide a project-specific macro spelling with
`-lifetime-safety-lifetimebound-macro=...`.
If no spelling is configured, use a visible macro whose replacement
tokens spell the attribute, preferring the most recently defined
matching macro, and fall back to `[[clang::lifetimebound]]` or
`__attribute((lifetimebound))` otherwise.
Closes https://github.com/llvm/llvm-project/issues/200232
GCE: Apply public-image label on GCE images
Update the GCE image creation process to automatically apply the
'public-image=true' label when publishing new images. This aligns
with standard labeling expectations for images hosted in public
projects.

ddb - Try AcpiReset() when invoking DDB's reset command.
- This allows some modern notebooks to successfully reset from DDB, where
the classic outb(0x64, 0xFE) method no longer works. For some notebooks,
we'll also need to support EFI Reset here, but that will require further
work.
efirt - Register EFI Reset with the shutdown_final EVENTHANDLER.
- This adds a safeguard to efi_enter() to fail gracefully when called from
a kernel thread, where curthread->td_lwp is NULL.
- Further work is needed to allow EFI Reset to work more simply without
messing with the current LWP's vmspace.
[BOLT][AArch64] Align tentative layout bases using per-section alignment (#204262)
Move `AssignSections` pass before `AlignerPass` so it can record the max
code alignment per output section, then align the tentative hot/cold
section bases using the recorded alignment, which makes tentative layout
better match actually emitted.
[Clang][UBSan] Use EmitCheckedLValue for C++ trivial operator= operands (#203737)

* for the LHS (`lhs->` not handled yet), and
* for the RHS also for function call syntax.
crashme: Fix building with GCC 14 and GCC 15.
This code makes frequent use of K&Risms such as implicit
function declarations, implicit int, etc. Fix a few and
force an older C standard to ensure this keeps building.
