Add method to query the sign of a NAN.
In writing some range-op entries I noticed we don't have a way to
query the sign of the NAN in a range, unless the range only contains
NAN, in which case you can just use frange::signbit_p. This patch
adds a method that returns TRUE if there exists the possiblity of a
NAN and we know its sign.
gcc/ChangeLog:
* value-range.h (frange::nan_signbit_p): New.
