frange: Implement nan_state class [PR109008]
This patch implements a nan_state class, that allows us to query or
pass around the NANness of an frange. We can store +NAN, -NAN, +-NAN,
or not-a-NAN with it.
I tried to touch as little as possible, leaving other cleanups to the
next release. For example, we should replace the m_*_nan fields in
frange with nan_state, and provide relevant accessors to nan_state
(isnan, etc).
PR tree-optimization/109008
gcc/ChangeLog:
* value-range.cc (frange::set): Add nan_state argument.
* value-range.h (class nan_state): New.
(frange::get_nan_state): New.
