Nemanja Ivanovic 4821411347 [DAGCombine] Fix splitting indexed loads in ForwardStoreValueToDirectLoad() ...

In DAGCombiner::visitLOAD() we perform some checks before breaking up an indexed
load. However, we don't do the same checking in ForwardStoreValueToDirectLoad()
which can lead to failures later during combining
(see: https://bugs.llvm.org/show_bug.cgi?id=45301).

This patch just adds the same checks to this function as well.
