[PATCH] D105589: [ARM] Move the creation of VBICIMM and VORRIMM to lowering

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

If you just want to delay the combine, I'd suggest just adding a `DCI.isAfterLegalizeDAG()` to the existing DAGCombine.  Doing it during lowering can lead to weird results; for example, AArch64 currently does this, and there's testcase where we end up with `orr v0.2s, #0`.
