[DXIL] Define and generate DXILAttribute and DXILProperty (#117072)
- Redefines `DXILAttribute` to denote a function attribute, compatible
to how it was define in DXC/LLVM 3.7
- Fix how `DXILAttribute` is emitted to be a struct of set attributes
instead of an "or" of the enums
- Implement the lowering of `DXILAttribute` to LLVM function attributes
in `DXILOpBuilder.cpp`. A custom mapping is defined.
- Audit all current ops to specify the correct attributes consistent
with DXC. This is done here to allow for testing.
- Update testcases in `llvm/test/CodeGen/DirectX` of all ops with
attributes to match that attributes are set
- Update testcases of ops that had previously incorrectly set attributes
to check there is no attributes set
- Defines `DXILProperty` to denote the other type of attributes from DXC
used to query properties.
- Emit `DXILProperty` as a struct of set attributes.
- Updates `DXIL.td` to specify applicable `DXILProperty`s on ops

Note: `DXILProperty` was referred to as 'queryable attributes' in design
discussion. Changed to property to allow for better expression in
`DXIL.td`

[HLSL][SPIRV]Add SPIRV generation for HLSL dot (#104656)
This adds the SPIRV fdot, sdot, and udot intrinsics and allows them to
be created at codegen depending on the target architecture. This
required moving some of the DXIL-specific choices to DXIL instruction
expansion out of codegen and providing it with at a more generic fdot
intrinsic as well.

Removed some stale comments that gave the obsolete impression that type
conversions should be expected to match overloads.

The SPIRV intrinsic handling involves generating multiply and add
operations for integers and the existing OpDot operation for floating
point.

New tests for generating SPIRV float and integer dot intrinsics are
added as well as expanding HLSL tests to include SPIRV generation

Used new dot product intrinsic generation to implement normalize() in SPIRV

Incidentally changed existing dot intrinsic definitions to use
DefaultAttrsIntrinsic to match the newly added inrinsics

Fixes #88056

[DXIL] Add DXIL version-specific TableGen specification and implementation of DXIL Ops (#97593)
Update TableGen specification of DXIL Op records in DXIL.td per the
current design document.

- Facilitate specification of overloads, shader stage and attributes
predicated on DXIL Ops predicated DXIL version.

Implement functionality to consume in TableGen backend, DXILEmitter, the
above specification enhancements, and generate C++ code (in
(DXILOperations.inc) that represents properties of DXIL Ops, associated
type declarations and corresponding accessor functions.

Changes to DXIL Op Lowering pass to consume the DXIL Op representation
generated by the TableGen back end.

Add mtriple with the required shader model version to commandline of
tests.

[DXIL] Add Float Dot Intrinsic Lowering (#86071)
Completes #83626
- `CGBuiltin.cpp` - modify `getDotProductIntrinsic` to be able to emit
`dot2`, `dot3`, and `dot4` intrinsics based on element count
- `IntrinsicsDirectX.td` - for floating point add `dot2`, `dot3`, and
`dot4` inntrinsics -`DXIL.td` add dxilop intrinsic lowering for `dot2`,
`dot3`, & `dot4`.
- `DXILOpLowering.cpp` - add vector arg flattening for dot product. 
- `DXILOpBuilder.h` - modify `createDXILOpCall` to take a smallVector
instead of an iterator
- `DXILOpBuilder.cpp` - modify `createDXILOpCall` by moving the small
vector up to the calling function in `DXILOpLowering.cpp`.
- Moving one function up gives us access to the `CallInst` and
`Function` which were needed to distinguish the dot product intrinsics
and get the operands without using the iterator.
