``` - add clang builtin to Builtins.td
- link builtin in hlsl_intrinsics
- add codegen for spirv intrinsic and two directx intrinsics to retain
signedness information of the operands in CGBuiltin.cpp
- add semantic analysis in SemaHLSL.cpp
- add lowering of spirv intrinsic to spirv backend in
SPIRVInstructionSelector.cpp
- add lowering of directx intrinsics to WaveActiveOp dxil op in
DXIL.td
- add test cases to illustrate passespendent pr merges.
```
