As a follow up from D149889 <https://reviews.llvm.org/D149889>, this patch passes in an explicit AccessTy
in SLP (and getPointersChainCost) to get more accurate GEP costs.

It also as adds a helper function to extract the access type of an
already materalized GEP and pass that to getGEPCost, provided the GEP
has exactly one user.
