Raw (as in ByteAddress) buffer accesses in DXIL must specify
ElementIndex as undef, and Structured buffer accesses must specify a
value. Ensure that we do this correctly in DXILResourceAccess, and
enforce that the operations are valid in DXILOpLowering.
Fixes#173316
Removes uniformity bit from resource initialization intrinsics `llvm.{dx|spv}.resource.handlefrombinding` and `llvm.{dx|spv}.resource.handlefromimplicitbinding`. The flag currently always set to `false`. It should be derived from resource analysis and not provided by codegen.
Closes#135452
Adds resource name argument to `llvm.dx.handlefrombinding` and `llvm.dx.handlefromimplicitbinding` intrinsics.
SPIR-V currently does not seem to need the resource names so this change only affects DirectX binding intrinsics.
