c278dccfd0 AMDGPU: Remove SITypeRewriter 
This was an old workaround for using v16i8 in some old intrinsics
for resource descriptors.

dad6e61ce7 [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

57c58d3969 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.
