[InstCombine] Support nested GEPs in OptimizePointerDifference (#142958)
Currently OptimizePointerDifference() only handles single GEPs with a
common base, not GEP chains. This patch generalizes the support to
nested GEPs with a common base.
Finding the common base is a bit annoying because we want to stop as
soon as possible and not recurse into common GEP prefixes.
This helps avoids regressions from
