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. Fixes: https://bugs.llvm.org/show_bug.cgi?id=45301 Differential revision: https://reviews.llvm.org/D76778
