[HLSL][DirectX] Remove uniformity bit from resource initialization intrinsics (#155332) 
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

[DirectX] Add resource name argument to llvm.dx.handlefrom[implicit]binding intrinsics (#139991) 
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.

[DirectX] Match DXC when storing RWBuffer<float> (#129911) 
Update the lowering of `llvm.dx.resource.store.typedbuffer` to match DXC
and repeat the first element in cases where we are storing fewer than 4
elements.

[DirectX][SPIRV] Consistent names for HLSL resource intrinsics (#120466) 
Rename HLSL resource-related intrinsics to be consistent with the naming
conventions discussed in [wg-hlsl:0014].

This is an entirely mechanical change, consisting of the following
commands and automated formatting.

```sh
git grep -l handle.fromBinding | xargs perl -pi -e \
  's/(dx|spv)(.)handle.fromBinding/$1$2resource$2handlefrombinding/g'
git grep -l typedBufferLoad_checkbit | xargs perl -pi -e \
  's/(dx|spv)(.)typedBufferLoad_checkbit/$1$2resource$2loadchecked$2typedbuffer/g'
git grep -l typedBufferLoad | xargs perl -pi -e \
  's/(dx|spv)(.)typedBufferLoad/$1$2resource$2load$2typedbuffer/g'
git grep -l typedBufferStore | xargs perl -pi -e \
  's/(dx|spv)(.)typedBufferStore/$1$2resource$2store$2typedbuffer/g'
git grep -l bufferUpdateCounter | xargs perl -pi -e \
  's/(dx|spv)(.)bufferUpdateCounter/$1$2resource$2updatecounter/g'
git grep -l cast_handle | xargs perl -pi -e \
  's/(dx|spv)(.)cast.handle/$1$2resource$2casthandle/g'
```

[DirectX] Run DXILFinalizeLinkage earlier in the pipeline (#117950) 
This moves DXILFinalizeLinkage before the DXIL op lowering passes so
that it doesn't end up internalizing any of the `dx.op.*` functions.
This also exposed a bug when the pass is run on a module with intrinsics
in them - marking the intrinsics as internal will fail the validator.

Fixes #117761

[DirectX] Lower @llvm.dx.typedBufferStore to DXIL ops 
The `@llvm.dx.typedBufferStore` intrinsic is lowered to `@dx.op.bufferStore`.
