[AMDGPU] merge 16bit mov pairs in post-RA peephole (#208625)
Address https://github.com/llvm/llvm-project/issues/207011. Add 5
patterns to merge 16bit mov pairs.
Since we hoist instruction which might cross the waitcnt boundary,
insert a new pass before waitcnt for this transformation

kasan: Fix the annotation for shadow map checks in atomic_load_*
atomic_load_* is a read, not a write. Otherwise KASAN will report a
use-after-free via atomic_load_* as a write rather than a read.

jail: Simplify refcount manipulation routines
- refcount_acquire() returns the old value, use that to assert that the
old value was non-zero.
- refcount_release() already asserts that the refcount value is
non-zero, so don't bother asserting that again in the jail code.
- Use __diagused instead of having separate implementations for
INVARIANTS and !INVARIANTS.
No functional change intended.

jail: Fix a race in prison_deref()
If we're killing a jail which has some user refs pending, then we would
first drop our ref and then kill all processes in the prison. However,
it's possible for the prison to be freed before we finish that
operation, generally if the processes exit on their own before
prison_proc_iterate() returns.
Thus, defer the release of the prison refcount until after we've killed
all procs.

[lld][test] Use LLVM helpers for input file discovery (#220404)
This was a suggestion on #220340 to avoid the custom env var handling
and use the `getInputFileDirectory` helper from the LLVM support library
[MLIR][XeGPU] Add MXFP fp8 WG GEMM tests and use shared input set (#225944)
Adds four workgroup-level tests, updates two and renames one, so that
seven tests covering bf16, mx-fp4 and mx-fp8 exercise the same
arithmetic on the same operand values and check against the same
expected result.
1. simple_mxfp_gemm -> simple_mxfp_gemm_F4 - renamed, for consistency
with the F4/F8 suffixes used by the quantize and dequantize tests
2. (new) simple_gemm_bf16 - non-quantized bf16 GEMM at the MXFP problem
size, as the unquantized comparison point, and where the shared input
set is documented
3. (new) simple_mxfp_gemm_F8 - f8E5M2 operands with f8E8M0FNU scales
4. (new) simple_mxfp_gemm_dequantizeB_F8
5. (new) simple_mxfp_gemm_quantizeA_F8 - fp8 counterparts of the
existing fp4 tests
6. simple_mxfp_gemm_dequantizeB_F4 and simple_mxfp_gemm_quantizeA_F4 are
updated in place.

[Analysis][RISCV] More accurately estimate the cost of strided vector loads (#175135)
For small constant strides, attempt to predict the amount of coalescing
that will be done by the target machine to give a better cost estimate.
Currently, strided loads/stores are costed as having a cost of 1 per
element (i.e. being equivalent to scalar loads/stores).

mips: fix rdhwr emulation wrt TLB misses on loading the faulting instruction.
Use tlbp to probe the TLB for an entry for the page containing the
instruction to emulate, and fail to slow path if it doesn't exist.
A TLB miss (nested exception) on the instruction load would otherwise
land in user_gen_exception and clobber this routine's v0, since the
exception PC isn't saved again while EXL is set.
PR/60664 mips: rdhwr emulation corrupts v0 on nested TLB miss...
This patch is based on the diff included in the PR, but updated by me
to improve register save / restore in both the fast and slow paths.
The mf* instructions in user_gen_exception_common are shuffled down
to maintain the same number of stores (4) between each mf* in
user_gen_exception_common and user_gen_exception_common2
