Subject: [PATCH] [HLSL] Implementation the `degrees` intrinsic
- add degrees builtin
- link degrees api in hlsl_intrinsics.h
- add degrees intrinsic to IntrinsicDirectX.td
- add degrees intrinsic to IntrinsicSPIRV.td
- add lowering from clang builtin to dx/spv intrinsics in
CGBuiltin.cpp
- add semantic checks to SemaHLSL.cpp
- add expansion of directx intrinsic to llvm fmul for DirectX in
DXILIntrinsicExpansion.cpp
- add mapping to spir-v intrinsic in SPIRVInstructionSelector.cpp
- add test coverage:
- degrees.hlsl -> check hlsl lowering to dx/spv degrees intrinsics
- degrees-errors.hlsl/half-float-only-errors ->
check semantic warnings
- hlsl-intrinsics/degrees.ll -> check lowering of spir-v
degrees intrinsic to SPIR-V backend
- DirectX/degrees.ll -> check expansion and scalarization of
directx degrees intrinsic to fmul
