[libunwind][PPC64] Fix unw_getcontext corrupting callee-saved VSX registers on LE (#198371)
This is the first of two independent fixes for libunwind on ppc64le
(ELFv2 ABI, little-endian), where two separate bugs together cause
SIGSEGV during backtracing. This commit addresses the VSX register
corruption; the TOC-restore fault is handled in a follow-up. Both
were discovered while debugging lang/rust build failures with
RUST_BACKTRACE=1 on FreeBSD/powerpc64le (IBM POWER9).
On ppc64le, `unw_getcontext` saves each VS register with an in-place
`xxswapd n, n` followed by `stxvd2x`. The swap is needed because
`stxvd2x` stores doublewords in the wrong order on LE. However, the
macro never applies a second `xxswapd` to restore the register after
the store, so all 64 VS registers are permanently corrupted on return
from `unw_getcontext`.
This affects every callee-saved VSX register: f14-f31 (VSR14-VSR31)
and VR20-VR31 (VSR52-VSR63). After `_Unwind_Backtrace` returns, any
code that uses these registers sees wrong values. In practice this

[Clang] Don't build static analyzer if disabled (#212024)
Even if the static analyzer is disabled, it still gets built into the
dylib. Unit tests and tools already get disables, so also stop building
the library. This reduces the time needed to build a dylib clang by
8-9%.
clang/AMDGPU: Rename amdgcn triples to amdgpu in cc1 tests (14)
Replace the legacy amdgcn architecture name with amdgpu in various
test triples. This set of updates covers cases that did not have
a set -target-cpu.

clang/AMDGPU: Migrate OpenMP cc1 tests to amdgpu triples (12)
Migrate the OpenMP offload cc1 tests to the new amdgpu triple scheme:
* -fopenmp-targets=amdgcn-amd-amdhsa -> -fopenmp-targets=amdgpu-amd-amdhsa
(the offload toolchain triple, the generic amdgpu arch).
* The device -triple amdgcn-amd-amdhsa -> amdgpu-amd-amdhsa, or to the
specific subarch triple (dropping -target-cpu) where a -target-cpu was
present.
Autogenerated CHECK lines are regenerated, and the few -Wopenmp-target-
exception diagnostics that embed the triple string are updated. Tests that
intentionally assert the "target-cpu" function attribute are left unchanged.

clang/AMDGPU: Migrate cc1 tests to subarch triples (11)

subarch triple form, dropping the redundant -target-cpu.

DAG: Stop legalizing poison to undef (#211890)
Previously all targets would expand poison to undef, which was a
shortcut taken when poison was introduced.
Introduces a new dedicated poison matcher in tablegen; this avoids
multiple opcode changes, and avoids some problematic contexts that
couldn't deal with PatFrags.
This probably should be legal by default for all legal types.

misc/ollama: update 0.32.1 → 0.32.3
What's Changed:
* Fixed model downloads that stall before sending data.
* Improved integrations: restored Claude Code Channels,
fixed Anthropic thinking streams, and made Hermes
Desktop respect --force-build.
* Expanded GPU support with CUDA on Windows ARM64, B200
support through CUDA 12, and lower memory use on Linux
CUDA/ROCm iGPUs.
* Added chat, thinking, and tool calling support for
Laguna 2.1 models, including a Metal inference fix.
* Fixed GLM tool calls being silently dropped at the end
of generation.
* Updated the MLX and llama.cpp engines.

[ThreadSafety] Fix C++20 build (#212042)
In C++20 (P1008R1 https://wg21.link/p1008r1), aggregates are prohibited
from having any user-declared constructors, even if they are = delete or
= default.
[DomTree] Remove support for unnumbered graphs (#212026)
After VPlan, all our in-tree users of the dominator tree have numbered
nodes. Remove the support for unnumbered graphs.
Also slightly simplify the numbering for pre-dominator trees to avoid an
extra +1 on every node number.

"Toolchain and infrastructure:
- 'zerocopy' crates: update to v0.8.54 to fix a modpost error under
'CONFIG_CC_OPTIMIZE_FOR_SIZE=y'.
There are actually two updates in the PR: the one to v0.8.52 is
fairly large and was originally not intended for a fixes PR, but the
actual fix landed in the v0.8.54 one. Thus I included both here.
The v0.8.52 update includes two things upstream added for us:
'--cfg no_fp_fmt_parse' to avoid a local workaround, and the new
'most_traits' feature.
The good news is that, after these updates, the delta with upstream
is now trivial: only an identifier prefix change and the SPDX
parentheses.

tail: Allow repetitive or contraditory options
Unlike its GNU counterpart, our tail(1) has always errored out if given
repetitive or contradictory options, even prior to Keith Bostic's 1991
reimplementation. There is no good reason to continue to do so, not
even tradition, since many other commands (including head(1)) simply
apply the rightmost option in cases like this.

[test] libatexit: leverage __{BEGIN,END}_DECLS
This change converts the longhand form of `extern "C" {` and its
corresponding `}` into `__BEGIN_DECLS` and `__END_DECLS`, respectively.
The new form is much easier to grep for and is a best practice to use in
the FreeBSD tree.
This is meant to be a non-functional change.
