utils.c (MAX_FIXED_MODE_SIZE): Delete.

	* gcc-interface/utils.c (MAX_FIXED_MODE_SIZE): Delete.
	(create_field_decl): Update description.  In a packed record, round
	the size up to a byte boundary only if the field's type has BLKmode.
	* gcc-interface/gigi.h (create_field_decl): Update description.
