[PATCH] use build_function_type_list a few places in the ObjC frontend

[Nathan Froyd]

Just as $SUBJECT suggests.  All the other uses of
build_function_type_list are tied up with get_arg_type_list and will
therefore have to wait for a better FUNCTION_TYPE builder.

Tested on x86_64-unknown-linux-gnu.  IIUC the changes to
objc-next-runtime-abi-02.c would not be tested on that platform, so it
would be helpful to have a Darwin tester double-check my work.

OK to commit?

        * objc-act.c (synth_module_prologue): Call build_function_type_list
        instead of build_function_type.
        * objc-next-runtime-abi-02.c (next_runtime_02_initialize):
        Likewise.
