  Log Message:
  -----------
  [DirectX] Make dx.RawBuffer an op that can't be replaced (#154620)

fixes #152348

SimplifyCFG collapses raw buffer store from a if\else load into a
select.

This change prevents the TargetExtType dx.Rawbuffer from being replace
thus preserving the if\else blocks.

A further change was needed to eliminate the phi node before we process
Intrinsic::dx_resource_getpointer in DXILResourceAccess.cpp
