This PR adds QuadReadAcrossX intrinsic support in HLSL with codegen for both DirectX and SPIRV backends. Resolves https://github.com/llvm/llvm-project/issues/99175. - [x] Implement QuadReadAcrossX clang builtin - [x] Link QuadReadAcrossX clang builtin with hlsl_intrinsics.h - [x] Add sema checks for QuadReadAcrossX to CheckHLSLBuiltinFunctionCall in SemaChecking.cpp - [x] Add codegen for QuadReadAcrossX to EmitHLSLBuiltinExpr in CGBuiltin.cpp - [x] Add codegen tests to clang/test/CodeGenHLSL/builtins/QuadReadAcrossX.hlsl - [x] Add sema tests to clang/test/SemaHLSL/BuiltIns/QuadReadAcrossX-errors.hlsl - [x] Create the int_dx_QuadReadAcrossX intrinsic in IntrinsicsDirectX.td - [x] Create the DXILOpMapping of int_dx_QuadReadAcrossX to 123 in DXIL.td - [x] Create the QuadReadAcrossX.ll and QuadReadAcrossX_errors.ll tests in llvm/test/CodeGen/DirectX/ - [x] Create the int_spv_QuadReadAcrossX intrinsic in IntrinsicsSPIRV.td - [x] In SPIRVInstructionSelector.cpp create the QuadReadAcrossX lowering and map it to int_spv_QuadReadAcrossX in SPIRVInstructionSelector::selectIntrinsic. - [x] Create SPIR-V backend test case in llvm/test/CodeGen/SPIRV/hlsl-intrinsics/QuadReadAcrossX.ll
