This change adds support for lowering the following X86 sqrt builtins to CIR operations: - __builtin_ia32_sqrtps (128-bit float vector sqrt) - __builtin_ia32_sqrtps256 (256-bit float vector sqrt) - __builtin_ia32_sqrtps512 (512-bit float vector sqrt) - __builtin_ia32_sqrtpd (128-bit double vector sqrt) - __builtin_ia32_sqrtpd256 (256-bit double vector sqrt) - __builtin_ia32_sqrtpd512 (512-bit double vector sqrt) - __builtin_ia32_sqrtph, __builtin_ia32_sqrtph256, __builtin_ia32_sqrtph512 (half precision) - __builtin_ia32_vsqrtbf16, __builtin_ia32_vsqrtbf16256, __builtin_ia32_vsqrtbf16512 (bfloat16) - __builtin_ia32_sqrtsh_round_mask, __builtin_ia32_sqrtsd_round_mask, __builtin_ia32_sqrtss_round_mask (masked rounding) Changes: - Added CIROps.h wrapper header for CIR operation declarations - Updated CIROps.td with SqrtOp definition (Pure trait, type-safe constraints) - Updated CIRTypeConstraints.td with float type constraints - Implemented builtin handling in CIRGenBuiltinX86.cpp - Added SqrtOp verification in CIRDialect.cpp - Implemented cir.sqrt lowering to llvm.sqrt.* intrinsics in LowerToLLVM.cpp/h - Added comprehensive test coverage in cir-sqrtps-builtins.c for X86 sqrt builtin variants The implementation follows existing CIR patterns and generates proper cir.sqrt operations for all sqrt builtin variants with appropriate type checking and lowering to LLVM IR.
