For ranges, PHIs don't need to process arg == def.
If an argument of a phi is the same as the DEF of the phi, then the range
on the incoming edge doesn't need to be taken into account since it can't
be anything other than itself.
* gimple-range-fold.cc (fold_using_range::range_of_phi): Don't import
a range from edge if arg == phidef.
