Summary: Delinearization fails to recognize the correct access
function

Wrong delinearization for accesses to "A" through "C".
Simialar to PR27013 delinearization of the attached test case generates a wrong
access function. The reasons also looks similar, both times the delinearization
analysis looks only at the first GEP in the IR but later we use
ScalarEvolution::getPointerBase to look though all GEPs.
