[LoopInterchange] Mark getAddRecCoefficient with static (#203624)
As this function is a file-scope non-member function, it's better to
mark it with static.
[LoopInterchange] Fix crash when followLCSSA returns constant (#203515)
Similar as the case in ##201069, `followLCSSA` may return a constant
value, but it was cast to Instruction unconditionally. We need to
explicitly check whether the returned value is an Instruction or not.
Fix #203375.
[SLP] Vectorize full insertvalue buildvector sequences
Treat a complete chain of insertvalue instructions building a homogeneous
literal struct from scalars as a buildvector, like insertelement sequences.
The scalars are vectorized into one vector; the aggregate is rebuilt from it
via a stack store + load, or stored directly when its only user is a store.
insertvalue is routed through the existing insertelement buildvector paths
(type/index helpers, reordering, tree build, cost model, min-bitwidth, and
codegen). Only single-index, non-vector inserts building from an undef
aggregate are handled.
Fixes #43353

[MLIR][XeVM] Add xevm.extf op as the inverse of xevm.truncf (#203124)
Add a new xevm.extf operation that extends f8/bf8/f4 values to f16/bf16,
mirroring the existing xevm.truncf op, together with its lowering in
XeVMToLLVM.
Lowering details (XeVMToLLVM):
- bf8/f8 -> f16 via __builtin_IB_bf8tohf_16 / __builtin_IB_hf8tohf_16.
- bf8/f8 -> bf16 via f16 -> f32 (convert_float16) -> bf16
(__builtin_IB_ftobf_16).
- e2m1 (fp4) -> f16/bf16 via __builtin_IB_shfl_idx4_lut and
__builtin_IB_shfl_idx4_to_fp16_8_packed (LUT 7 for f16, 5 for bf16).
Adds the op definition and verifier, conversion/roundtrip/invalid unit
tests, and f8 and fp4 GPU round-trip integration tests.
Adds arith.extf to xevm.extf lowering and arith.truncf to xevm.truncf
lowering in XeGPU to XeVM conversion and unit tests.

[AMDGPU] NFC: Drop constexpr from getFlavor*Name functions (#203603)
It seems specifying these as constexpr was causing some buildbot

libtest: Simplify the test(3) & test_driver(3) APIs.
- Signal errors in setup/teardown functions using a plain
'bool'.
- Do not place test tags and test descriptions in the C
source code for a test. These are better placed elsewhere
alongside other metadata associated with the test.
[Fuzzer] Use the internal shell by default (#203450)
The external shell is going away soon and the internal shell is superior
in most ways (platform compatibility, performance, debugging). This now
causes no test failures and is blocking deprecation of the external
shell, so switch over.
[ConstraintElim] Add test with negative offset and NUW only GEP (NFC) (#203614)
Add test currently mis-compiled with NUW only GEP.

Fix contextual implicit conversions to int: with _Atomic (#203522)
PerformContextualImplicitConversion was performing
default-lvalue-conversions, then basing decisions on viable conversion
functions on this type However, when we then went to add the candidates
we were using the 'old' value (pre-conversion) of the type, resulting in
us regaining the lost 'atomic' from the default Lvalue conversion.
This patch updates the 'from' variable to be the converted value so all
conversions are done post-conversion.
