Make irange dependency explicit for range_of_ssa_name_with_loop_info.
Even though ranger is type agnostic, SCEV seems to only work with integers. This patch removes some FIXME notes making it explicit that bounds_of_var_in_loop only works with iranges. Tested on x86-64 Linux. gcc/ChangeLog: * gimple-range-fold.cc (fold_using_range::range_of_phi): Only query SCEV for integers. (fold_using_range::range_of_ssa_name_with_loop_info): Remove irange check.
