frange::maybe_isnan() should return FALSE for undefined ranges.

Undefined ranges have undefined NAN bits.  We can't depend on them,
as they may contain garbage.  This patch returns false from
maybe_isnan() for undefined ranges (the empty set).

gcc/ChangeLog:

* value-range.h (frange::maybe_isnan): Return false for
undefined ranges.
