[InstCombine] Strip leading zero indices from GEP (#155415) ...

GEPs are often in the form `gep [N x %T], ptr %p, i64 0, i64 %idx`.
Canonicalize these to `gep %T, ptr %p, i64 %idx`.

This enables transforms that only support one GEP index to work and
improves CSE.

Various transforms were recently hardened to make sure they still work
without the leading index.
