This PR adds QuadReadAcrossY intrinsic support in HLSL with codegen for both DirectX and SPIRV backends. Resolves https://github.com/llvm/llvm-project/issues/99176. - [x] Implement `QuadReadAcrossY` clang builtin, - [x] Link `QuadReadAcrossY` clang builtin with `hlsl_intrinsics.h` - [x] Add sema checks for `QuadReadAcrossY` to `CheckHLSLBuiltinFunctionCall` in `SemaChecking.cpp` - [x] Add codegen for `QuadReadAcrossY` to `EmitHLSLBuiltinExpr` in `CGBuiltin.cpp` - [x] Add codegen tests to `clang/test/CodeGenHLSL/builtins/QuadReadAcrossY.hlsl` - [x] Add sema tests to `clang/test/SemaHLSL/BuiltIns/QuadReadAcrossY-errors.hlsl` - [x] Create the `int_dx_QuadReadAcrossY` intrinsic in `IntrinsicsDirectX.td` - [x] Create the `DXILOpMapping` of `int_dx_QuadReadAcrossY` to `123` in `DXIL.td` - [x] Create the `QuadReadAcrossY.ll` and `QuadReadAcrossY_errors.ll` tests in `llvm/test/CodeGen/DirectX/` - [x] Create the `int_spv_QuadReadAcrossY` intrinsic in `IntrinsicsSPIRV.td` - [x] In SPIRVInstructionSelector.cpp create the `QuadReadAcrossY` lowering and map it to `int_spv_QuadReadAcrossY` in `SPIRVInstructionSelector::selectIntrinsic`. - [x] Create SPIR-V backend test case in `llvm/test/CodeGen/SPIRV/hlsl-intrinsics/QuadReadAcrossY.ll`
