Adds the WaveActiveMin intrinsic from #99169. I think I did all of the required things on the checklist: - [x] Implement `WaveActiveMin` clang builtin, - [x] Link `WaveActiveMin` clang builtin with `hlsl_intrinsics.h` - [x] Add sema checks for `WaveActiveMin` to `CheckHLSLBuiltinFunctionCall` in `SemaChecking.cpp` - [x] Add codegen for `WaveActiveMin` to `EmitHLSLBuiltinExpr` in `CGBuiltin.cpp` - [x] Add codegen tests to `clang/test/CodeGenHLSL/builtins/WaveActiveMin.hlsl` - [x] Add sema tests to `clang/test/SemaHLSL/BuiltIns/WaveActiveMin-errors.hlsl` - [x] Create the `int_dx_WaveActiveMin` intrinsic in `IntrinsicsDirectX.td` - [x] Create the `DXILOpMapping` of `int_dx_WaveActiveMin` to `119` in `DXIL.td` - [x] Create the `WaveActiveMin.ll` and `WaveActiveMin_errors.ll` tests in `llvm/test/CodeGen/DirectX/` - [x] Create the `int_spv_WaveActiveMin` intrinsic in `IntrinsicsSPIRV.td` - [x] In SPIRVInstructionSelector.cpp create the `WaveActiveMin` lowering and map it to `int_spv_WaveActiveMin` in `SPIRVInstructionSelector::selectIntrinsic`. - [x] Create SPIR-V backend test case in `llvm/test/CodeGen/SPIRV/hlsl-intrinsics/WaveActiveMin.ll But as some of the code has changed and was moved around (E.G. `CGBuiltin.cpp` -> `CGHLSLBuiltins.cpp`) I mostly followed how `WaveActiveMax()` is implemented. I have not been able to run the tests myself as I am unsure which project runs the correct test. Any guidance on how I can test myself would be helpful. Also added some tests to the offload-test-suite https://github.com/llvm/offload-test-suite/pull/478
