re PR debug/90231 (ivopts causes <optimized away> iterator in the loop)

PR debug/90231
* tree-ssa-loop-ivopts.c (get_debug_computation_at): New function.
(remove_unused_ivs): Use it instead of get_computation_at.  When
choosing best candidate, only consider candidates where
get_debug_computation_at actually returns non-NULL.
