[PATCH] D145301: Add more efficient vector bitcast for AArch64

[Markus Everling via Phabricator via llvm-commits]

Actually no, those functions I linked to might not be doing what I think they're doing. There's also this, which might be the right one? https://github.com/llvm/llvm-project/blob/cb96eba27cd18ecf8041bf1b9a5c7e197f7a2749/llvm/lib/CodeGen/SelectionDAG/LegalizeVectorOps.cpp#L692-L701

Either way, the right move is probably to either add a target specific lowering that uses the bit-and method to AArch64ISel or to add it as a general fallback to all targets.
