[Clang] Adjust NTTP depths in IsAtLeastAsConstrained (#209445)
The default transform for NTTP, which is no-op, doesn't help if we need
to adjust their depths when comparing constraints.

AMDGPU/GlobalISel: Handle G_BITCAST for 16 bit extendedLLTs
Handle bitcast between i16 and f16/bf16.
For true16 this was already legal, make it legal in regbanklegalize as well.
For non-true16 widen it using G_ANYEXT to i32 and G_TRUNC to dst.
The "i32 G_ANYEXT f16/bf16" and "f16/bf16 G_TRUNC i32" are already legal,
for example these are generated by common CallLowering argument lowering.
[ASan][AIX] Intercept __linux_vec_malloc/__linux_vec_calloc/__linux_realloc (#209359)
On AIX PASE, when `__VEC__` and `_ALL_SOURCE` are defined, the XL
compiler frontend lowers calls to vec_malloc/vec_calloc/realloc to
internal symbols named `__linux_vec_malloc`, `__linux_vec_calloc`, and
`__linux_realloc` instead of the standard
`vec_malloc`/`vec_calloc`/`realloc` names. These symbols were not
intercepted, so allocations made through them bypassed ASan entirely, no
redzone poisoning, no use-after-free or overflow detection.
This adds interceptors for `__linux_vec_malloc`, `__linux_vec_calloc`,
and `__linux_realloc`, following the same pattern as the existing
`vec_malloc`/`vec_calloc` interceptors (#175584): `__linux_vec_malloc`
and `__linux_vec_calloc` route through
`asan_vec_malloc`/`asan_vec_calloc` (16-byte aligned), and
`__linux_realloc` routes through the existing `asan_realloc`.

[SLP]Do not blacklist ordered-reduction operands on failed root attempt
An ordered reduction pulls its leaf operands into ReductionOps via the
fallback in matchAssociativeReduction. When such a reduction fails to
vectorize, marking every reduction op as analyzed also blocks those leaves,
which may still be valid reduction roots on their own.

AMDGPU: Migrate CodeGen tests to amdgpu subarch triple (27)
Mechanically migrate the command-line target spelling on llc/opt RUN lines in
llvm/test/CodeGen/AMDGPU from -mtriple=amdgcn ... -mcpu=<gfx> to the folded
subarch triple form (e.g. -mtriple=amdgpu9.00-amd-amdhsa), dropping the
redundant -mcpu.

[orc-rt] Move ErrorTest death tests to an ErrorDeathTest suite. (#209476)
GoogleTest recommends putting death tests in a suite whose name ends in
"DeathTest": it runs those suites before all others, which avoids the
fork-after-threads hazard that can make death tests flaky.
Move the nine EXPECT_DEATH tests in ErrorTest.cpp from the ErrorTest
suite to a new ErrorDeathTest suite. Only the suite name changes; the
test bodies are untouched.
