[PATCH] D117457: [DAG] Extend SearchForAndLoads with any_extend handling

[Hans Wennborg via Phabricator via llvm-commits]

hans added a comment.

This is causing builds to fail with an assert:

llvm/lib/CodeGen/SelectionDAG/DAGCombiner.cpp:5638: bool (anonymous namespace)::DAGCombiner::BackwardsPropagateMask(llvm::SDNode *): Assertion `NewLoad && "Shouldn't be masking the load if it can't be narrowed"' failed.

See https://bugs.chromium.org/p/chromium/issues/detail?id=1288202#c1 for a reproducer.

I'll revert this until it can be fixed.
