[CIR][LLVMLowering] Add LLVM lowering for unary fp2fp builtins #651

Closed Lancern closed 1 month ago

Lancern commented 1 month ago

This patch adds LLVM lowering support for unary fp2fp builtins.

Those builtins that should be lowered to runtime function calls are lowered to such calls during lowering prepare. Other builtins are lowered to LLVM intrinsic calls during LLVM lowering.
