h8300.c (extra_pop): Remove unused variable.

        * h8300/h8300.c (extra_pop): Remove unused variable.
        (current_function_anonymous_args): Likewise.
        (function_prologue): Remove incorrect varargs/stdarg
        related code.
        (function_epilogue): Likewise.
        (function_arg): Never pass unnamed arguments in registers.
        * h8300.h (LONG_LONG_TYPE_SIZE): Use 64bits when ints are
        32bits.
        (SETUP_INCOMING_VARARGS): Remove definition.
