testsuite: Fix up anon4.C test for excess precision targets

The g++.dg/reflect/anon4.C test FAILs on i686-linux, because with
extended precision the store to .c rounds to double precision, but comparison
of it against 3.14 constant doesn't.

	* g++.dg/reflect/anon4.C (test): Use (double) 3.14 instead of 3.14 in
	comparisons.
