Remove dominator check in fold_using_range::range_of_phi.
Revert the following patch, as it was an artifact of diagnostic code
being run with improper IL.
commit 64b80b8819f9ea74712625bceb0ec4388e25f67d

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.
gcc/ChangeLog:
* gimple-range-fold.cc (fold_using_range::range_of_phi):
Remove dominator check.
