Fixes #1483 'remove_unused_subroutines' method expects a 'GlobalSubrs' attribute but the 'desubroutinize' method deletes it. We don't have to call 'remove_unused_subroutines' at the end of 'desubroutinize' method, we can just delete all the local subroutines, and clear the GlobalSubrsIndex. Only call 'remove_unused_subroutines' method once, when we are not desubroutinizing.
