Make range_of_ssa_name_with_loop_info type agnostic.
gcc/ChangeLog: * gimple-range-fold.cc (fold_using_range::range_of_phi): Remove irange check. (tree_lower_bound): New. (tree_upper_bound): New. (fold_using_range::range_of_ssa_name_with_loop_info): Convert to vrange. * gimple-range-fold.h (range_of_ssa_name_with_loop_info): Change argument to vrange.
