[32/77] Check is_a <scalar_int_mode> before calling valid_pointer_mode
A future patch will make valid_pointer_mode take a scalar_int_mode
instead of a machine_mode. is_a <...> rather than as_a <...> is
needed here because we're checking a mode supplied by the user.

* c-attribs.c (handle_mode_attribute): Check for a scalar_int_mode
