* i386-tdep.c (i386_push_arguments, i386_store_struct_return): New
functions.
* config/i386/tm-i386.h (PUSH_ARGUMENTS): New macro.
(STORE_STRUCT_RETURN): Redefine in terms of
i386_store_struct_return.
(i386_push_arguments, i386_store_struct_return): New prototypes.
* config/i386/tm-i386v.h (STORE_STRUCT_RETURN): Remove. It's
definition was identical to the definition in "i386/tm-i386.h" so
the new definition should suffice too.
