* eval.c (evaluate_subexp_standard) [OP_OBJC_MSGCALL]: Support
platforms that use function descriptors. Prefer to use function
pointer types instead of function types.
* linespec.c (decode_objc): Support function descriptors. Fully
initialize SAL result.
* objc-lang.c (find_methods): Support function descriptors.
Do not require function symbol to point to text section.
* ppc-sysv-tdep.c (ppc64_sysv_abi_push_dummy_call): When calling
via a function pointer, use the descriptor it points to.
