[committed] Fix ipa/pr63551.c testcase

[Jakub Jelinek]

Hi!

This testcase fails on the 4.9 branch (where C89 is the default) on 32-bit
targets, because of
warning: this decimal constant is unsigned only in ISO C90
warning.  On the trunk it doesn't warn because we default to C11.  In any
case, the testcase also fails the same way before the r218205 fix and
succeeds with it if I add U suffix, so I've committed this fix to
trunk and 4.9 branches as obvious.

	PR tree-optimization/63551
	* gcc.dg/ipa/pr63551.c (fn2): Use 4294967286U instead of
	4294967286 to avoid warnings.
