	* c-common.c (constant_fits_type_p): Delete.
	(unsigned_conversion_warning): Delete.
	(conversion_warning): Integrate Wconversion warning from
	unsigned_conversion_warning.
	(convert_and_check): Integrate Woverflow warning from
	unsigned_conversion_warning.  Reorganize and simplify to avoid
	dependence upon the middle-end setting TREE_OVERFLOW on integral
	conversions, by using int_fits_type_p directly.
