[frange] Return false if nothing changed in union_nans().

When one operand is a known NAN, we always return TRUE from
union_nans(), even if no change occurred.  This patch fixes the
oversight.

gcc/ChangeLog:

* value-range.cc (frange::union_nans): Return false if nothing
changed.
(range_tests_floats): New test.
