Resolves #99221 Key points: For SPIRV backend, it decompose into a `dot` followed a `add`. - [x] Implement dot2add clang builtin, - [x] Link dot2add clang builtin with hlsl_intrinsics.h - [x] Add sema checks for dot2add to CheckHLSLBuiltinFunctionCall in SemaHLSL.cpp - [x] Add codegen for dot2add to EmitHLSLBuiltinExpr in CGBuiltin.cpp - [x] Add codegen tests to clang/test/CodeGenHLSL/builtins/dot2add.hlsl - [x] Add sema tests to clang/test/SemaHLSL/BuiltIns/dot2add-errors.hlsl - [x] Create the int_dx_dot2add intrinsic in IntrinsicsDirectX.td - [x] Create the DXILOpMapping of int_dx_dot2add to 162 in DXIL.td - [x] Create the dot2add.ll and dot2add_errors.ll tests in llvm/test/CodeGen/DirectX/
