This was an old workaround for using v16i8 in some old intrinsics
for resource descriptors.

David Stuttard 70e8bc1bf3 [AMDGPU] Add intrinsics for tbuffer load and store 
Intrinsic already existed for llvm.SI.tbuffer.store

Needed tbuffer.load and also re-implementing the intrinsic as llvm.amdgcn.tbuffer.*

Added CodeGen tests for the 2 new variants added.
Left the original llvm.SI.tbuffer.store implementation to avoid issues with existing code

Krzysztof Parzyszek 3bf4aeccd6 Do not consider subreg defs as reads when computing subrange liveness 
Subregister definitions are considered uses for the purpose of tracking
liveness of the whole register. At the same time, when calculating live
interval subranges, subregister defs should not be treated as uses.
