* gimple-ssa-sprintf.c (build_intmax_type_nodes): Look at

	UINTMAX_TYPE rather than SIZE_TYPE.  Add gcc_unreachable if
	intmax_t couldn't be determined.
	(format_integer): Make {,u}intmax_type_node no longer static,
	initialize them only when needed.  For z and t use
	signed_or_unsigned_type_for instead of assuming size_t and
	ptrdiff_t have the same precision.
