  |     [InstCombine] Canonicalize more geps with constant gep bases and constant offsets. (#110033)
  |     
  |     This is another small but hopefully not performance negative step to
  |     canonicalizing towards i8 geps. We looks for geps with a constant offset
  |     base pointer of the form `gep (gep @glob, C1), x, C2` and expand the gep
  | ... 2 lines of the commit log omitted.
