	* mips-tdep.c (mips_print_register): Print integers using
	print_scalar_formatted rather than duplicating all the
	CC_HAS_LONG_LONG and so on.
	(mips_push_dummy_frame): Use read_register_gen rather than using
	read_register and then putting it back in target format with
	store_unsigned_integer.  If registers are more than 4 bytes, give
	an error rather than have some registers overwrite other
	registers.
