Again, why the #ifdef? It seems like on most platforms, result_size will always
either 1, or if there are cases where there are already 2 results returned, then
BUILTIN_OBJECTPAIR_CALL is just an alias for BUILTIN_CALL on those platforms and
should be threaded through as such.

This is related to running the simulator version of the code 'natively' on
PowerPC. This is a useful feature, but I've removed for now as it cleans up the
common code.
