[DirectX] Update resource type names in DXIL metadata to include element type (#140937)
Update resource type names for globals variables that we generate in `DXILTranslateMetadata` pass to include element type. This change prevents duplicate types for identical resources and brings the DXIL metadata names it closer to what DXC generates.

[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.

[HLSL][NFC] Add resource globals created for metadata to test baseline (#140620)
Adds checks for resource globals that were created for DXIL metadata.
The names of the globals and the names of the types will be changing
soon. Adding these to the baseline will make it easier to see what is
changing.

[HLSL] Buffer handle globals should not be constants (#130231)
If these are constants their initializers will be removed by
InstCombine. Change them to not be constants and initialize them with
poison.

[HLSL][NFC] Update resource metadata tests to not use obsolete annotations (#130222)
Update resource metadata tests to generate metadata based on
`llvm.dx.resource.handlefrombinding` data collected in
`DXILResourceBindingAnalysis`.

- `UAVMetadata.ll` is updated, renamed to `uav_metadata.ll`, and placed
under `Metadata` directory in `llvm/test/CodeGen/DirectX`
- `srv_metadata.ll` is a new test for SRV resource metadata
- `cbuf.ll` and `legacy_cb_layout_{0|1}.ll` tests were merged into
`cbuffer_metadata.ll`
- `legacy_cb_layout_{2|3}.ll` tests we moved to `cbuffer.hlsl` in Clang
CodeGen because there were more of a layout than metadata tests

[DXIL][Analysis] Make sure resource accessors are contiguous (#128696)
When some resource types were present, but not all of them, we were
ending up in a situation where we would fail to initialize the `FirstX`
variables and get incorrect iterators.

Fixes #128560.

[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] Create symbols for resource handles (#119775)
We need to create symbols with "the original shape of resource and
element type" to put in the resource metadata in order to generate valid
DXIL.

Note that DXC generally doesn't emit an actual symbol outside of library
shaders (it emits an undef of a pointer to the type), but since we have
to deal with opaque pointers we would need a way to smuggle the type
through to match that. Instead, we simply emit symbols for now.

Fixed #116849

[DXIL] Consume Metadata Analysis information in passes (#108034)
- Changed `DXILTranslateMetadata::translateMetadata()` to consume DXIL
Metadata Analysis information. Subsumed into `DXILTranslateMetedata.cpp`
the functionality in `DXILMetadata.*` files - that are hence deleted.
- Changed `DXILPrepare` pass to consume DXIL Metadata Analysis
information.
- Renamed `ModuleMetadataInfo::ShaderStage` to
`ModuleMetadataInfo::ShaderProfile` to better convey what it represents.
- Updated `unknown` target shader stage specification in triples of a
couple of tests.
- Added new tests for additional verification of `DXILTranslateMetadata`
pass functionality.

[DXIL][Analysis] Collect Function properties in Metadata Analysis (#105728)
Basic infrastructure to collect Function properties in Metadata Analysis
- Add a `SmallVector` of entry properties to the metadata information.
- Add a structure to represent function properties. Currently
`numthreads` and shader kind properties of shader entry functions are
represented.

[DirectX] Register a few DXIL passes with the new PM
This wires up dxil-op-lower, dxil-intrinsic-expansion, dxil-translate-metadata,
and dxil-pretty-printer to the new pass manager, both as a matter of future
proofing the backend and so that they can be used more flexibly in tests.

A few arbitrary tests are updated in order to test the new PM path, and we drop
the "print-dxil-resource-md" pass since it's redundant with the pretty printer.

[DXIL][Analysis] Add validator version to info collected by Module Metadata Analysis (#104828)
Add Validator Version to information collected by Module Metadata
Analysis pass. An earlier change (#104040) added a default hardcoded
value for validator version to be associated with DXIL module created
during HLSL source compilation.

Add tests to verify validator version info collected
 - Updated existing tests
 - Added a test with validator version specified in DXIL metadata

[DXIL][Analysis] Add DXILMetadataAnalysis pass (#102079)
DXIL Metadata Analysis passes (one for legacy PM and one for new PM)
that collect following DXIL module metadata information in a structure
are added.
1. Shader Model version
2. DXIL version 
3. Shader Stage

Information collected using the legacy pass is verified by adding
additional test commands to existing metadata test sources.

[DirectX] remove string function attribute DXIL not allowed (#90778)
Remove string function attribute other than
"waveops-include-helper-lanes" and "fp32-denorm-mode".

Move DXILPrepareModulePass after DXILTranslateMetadataPass since
DXILTranslateMetadataPass needs to use attribute like hlsl.numthreads.

b861507912 [DIrectX backend] emit metadata for entry.
New named metadata "dx.entryPoints" is added to save all entries.

Each entry is in format of
!{ptr to function, name, signature, resource table, extra}

For compute shader, the extra will save num of threads in format of {i32 x, i32 y, i32 z}

For library profile, an empty entry will be added to save the resource table for the library.

Signature and resource table metadata is not generated yet.
