This avoids problems with inlining in genwrappers, which occurs after functions have been compiled. Compiling a function may cause some unused local vars to be removed from the list. Since a local var may be unused due to optimization, it is possible that a removed local var winds up beingused in the inlined version, in which case hilarity ensues. Fixes #5515.
