  [LLParser] Delete temp CallInst when error occurs

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.
