* ppc-sysv-tdep.c (ppc64_sysv_abi_push_dummy_call): Handle
TYPE_CODE_BOOL and TYPE_CODE_CHAR the same as TYPE_CODE_INT.
Handle TYPE_CODE_REF the same as TYPE_CODE_PTR.
Handle TYPE_CODE_METHOD the same as TYPE_CODE_FUNC.
Allow typedefs when checking for function pointer arguments.
Right-align small structs passed on the stack.
(ppc64_sysv_abi_return_value): Handle TYPE_CODE_BOOL and
TYPE_CODE_CHAR the same as TYPE_CODE_INT.
Handle TYPE_CODE_REF the same as TYPE_CODE_PTR.
