AMDGPU: Add some leaf intrinsics to isAlwaysUniform (#101925)
These would always be uniform anyway, but it shouldn't hurt to
mark them as always uniform. This will help use TTI::isAlwaysUniform
in
AMDGPU: Add some leaf intrinsics to isAlwaysUniform (#101925)
These would always be uniform anyway, but it shouldn't hurt to
mark them as always uniform. This will help use TTI::isAlwaysUniform
in place of proper uniformity analysis in trivial situations.

[AMDGPU] Add inreg support for SGPR arguments (#67182)
Function parameters marked with inreg are supposed to be allocated to
SGPRs. However, for compute functions, this is ignored and function
parameters are allocated to VGPRs. This fix modifies CC_AMDGPU_Func in
AMDGPUCallingConv.td to use SGPRs if input arg is marked inreg.

UniformityAnalysis offers all of the same features and much more, there is no reason left to use the legacy DAs.

[Analysis] Remove DA & LegacyDA
UniformityAnalysis offers all of the same features and much more, there is no reason left to use the legacy DAs.
See RFC: https://discourse.llvm.org/t/rfc-deprecate-divergenceanalysis-legacydivergenceanalysis/69538
- Remove LegacyDivergenceAnalysis.h/.cpp
- Remove DivergenceAnalysis.h/.cpp + Unit tests
- Remove SyncDependenceAnalysis - it was not a real registered analysis and was only used by DAs
- Remove/adjust references to the passes in the docs where applicable
- Remove TTI hook associated with those passes.
- Move tests to UniformityAnalysis folder.
- Remove RUN lines for the DA, leave only the UA ones.
- Some tests had to be adjusted/removed depending on how they used the legacy DAs.
