This sounds OK to me. Thanks for the fix.

Does this mean we don't have any tests for this code? Can we add one? It looks like the tests in llvm/test/CodeGen/AArch64/aarch64-vuzp.ll no longer trigger it, and I'm not sure how to make a simple reproducer that actually gets to this code as a BuildVector.
