Closes #99156. Tasks completed: - Implement `smoothstep` using HLSL source in `hlsl_intrinsics.h` - Implement the `smoothstep` SPIR-V target built-in in `clang/include/clang/Basic/BuiltinsSPIRV.td` - Add sema checks for `smoothstep` to `CheckSPIRVBuiltinFunctionCall` in `clang/lib/Sema/SemaSPIRV.cpp` - Add codegen for spv `smoothstep` to `EmitSPIRVBuiltinExpr` in `clang/lib/CodeGen/TargetBuiltins/SPIR.cpp` - Add codegen tests to `clang/test/CodeGenHLSL/builtins/smoothstep.hlsl` - Add spv codegen test to `clang/test/CodeGenSPIRV/Builtins/smoothstep.c` - Add sema tests to `clang/test/SemaHLSL/BuiltIns/smoothstep-errors.hlsl` - Add spv sema tests to `clang/test/SemaSPIRV/BuiltIns/smoothstep-errors.c` - Create the `int_spv_smoothstep` intrinsic in `IntrinsicsSPIRV.td` - In SPIRVInstructionSelector.cpp create the `smoothstep` lowering and map it to `int_spv_smoothstep` in `SPIRVInstructionSelector::selectIntrinsic` - Create SPIR-V backend test case in `llvm/test/CodeGen/SPIRV/hlsl-intrinsics/smoothstep.ll` - Create SPIR-V backend test case in `llvm/test/CodeGen/SPIRV/opencl/smoothstep.ll`
