The existing llvm\test\CodeGen\X86\vec_fpext.ll and llvm\test\CodeGen\X86\vec_int_to_fp.ll already demonstrate the correct optimized DAG codegen using the same IR as output in the clang\test\CodeGen\*-builtins.c here. Also, the aim is to keep the llvm\test\CodeGen\X86\*-intrinsics-fast-isel.ll tests in sync with the llvm\tools\clang\test\CodeGen\*-builtins.c equivalents.
