[PATCH] Print unsigned host-wide-int fitting INTEGER_CSTs regularly

[PATCH] Print unsigned host-wide-int fitting INTEGER_CSTs regularly

[Richard Guenther]

without resorting to hex printing of both high/low values.

Bootstrapped and tested on x86_64-unknown-linux-gnu, applied to trunk.

	* pretty-print.h (pp_unsigned_wide_integer): New.
	* tree-pretty-print.c (dump_generic_node): Print unsigned
	host-wide-int fitting INTEGER_CSTs with pp_unsigned_wide_integer.
