  Log Message:
  -----------
  [ConstraintElim] Use collectOffset instead of custom GEP idx iteration.

Use collectOffset to collect scaled indices and constant offset for GEP
instead of custom code. This simplifies the logic in decomposeGEP and
allows to handle all cases supported by the generic helper.
