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.
