Stream out endpoints for frange.
We only stream out the FP properties for global float ranges
(currently only NAN). The following patch adds the endpoints as well.
gcc/ChangeLog:
* value-range-storage.cc (frange_storage_slot::set_frange): Save
endpoints.
(frange_storage_slot::get_frange): Restore endpoints.
* value-range-storage.h (class frange_storage_slot): Add endpoint
fields.
