Do not query SCEV in range_of_phi unless dominators are available.

SCEV won't work without dominators and we can get called without
dominators from debug_ranger.

Another option would be to rename scev_initialized_p to something like
scev_available_p and move the check there.  For now, this will do.

gcc/ChangeLog:

* gimple-range-fold.cc (fold_using_range::range_of_phi): Check
dom_info_available_p.
