    1. Remove `Intrinsic::dx_normalize`
2. Remove `BI__builtin_hlsl_normalize`
3. Remove `BI__builtin_hlsl_normalize` Sema checks from `clang/lib/Sema/SemaHLSL.cpp`
4. Remove `getNormalizeIntrinsic` from `clang/lib/CodeGen/CGHLSLRuntime.h`
5. Remove emitting intrinsic from `clang/lib/CodeGen/CGBuiltin.cpp`
6. Remove `expandNormalizeIntrinsic` in `llvm/lib/Target/DirectX/DXILIntrinsicExpansion.cpp`
7.  Implement normalize algorithmicly in hlsl_intrinsics.h`
8.  add a pattern match for normalize as an InstCombine in `llvm/lib/Target/SPIRV/SPIRVPreLegalizerCombiner.cpp` to be able to still emit the normalize GL extention.
