Only functions with floating-point return type accepts fast-math flags. When adding such flags to function returning integer, we'll see a crash, because there's still an undeleted value referencing the argument. This patch manually removes the temporary instruction when error occurs. Reviewed By: arsenm Differential Revision: https://reviews.llvm.org/D78355
