[SCEV] Fix "quick and dirty" difference that could lead to assert (#70688)
The old algorithm would remove all operands matching %step SCEV when it
intended to only remove a single one. This lead to assert when
SCEVAddExpr was of the form %step + %step and potential miscompiles in
similar cases. Such SCEVs could be created when construction reached
depth thresholds.
Fixes #70348
