clang-p2996/llvm/test/CodeGen/AMDGPU/GlobalISel/llvm.amdgcn.struct.ptr.buffer.load.ll
Krzysztof Drewniak ab37937812 [AMDGPU] Use resource base for buffer instruction MachineMemOperands 
1. Remove the existing code that would encode the constant offsets (if
there were any) on buffer intrinsic operations onto their
`MachineMemOperand`s. As far as I can tell, this use of `offset` has
no substantial impact on the generated code, especially since the same
reasoning is performed by areMemAccessesTriviallyDisjoint().

2. When a buffer resource intrinsic takes a pointer argument as the
base resource/descriptor, place that memory argument in the value
field of the MachineMemOperand attached to that intrinsic.

This is more conservative than what would be produced by more typical
LLVM code using GEP, as the Value (for alias analysis purposes)
corresponding to accessing buffer[0] and buffer[1] is the same.
However, the target-specific analysis of disjoint offsets covers a lot
of the simple usecases.

Despite this limitation, the new buffer intrinsics, combined with
LLVM's existing pointer annotations, allow for non-trivial
optimizations, as seen in the new tests, where marking two buffer
descriptors "noalias" allows merging together loads and stores in a
"load from A, modify loaded value, store to B" sequence, which would
not be possible previously.

Depends on D147547
