Yep it should and the current patch adds it to the correct switch AFAICT. Might be good to add a run-line with m5/a19 to llvm/test/Transforms/LoopUnroll/AArch64/apple-unrolling.ll

To check the max-interleave factor is set correctly, it would probably be good to have a simple LoopVectorize interleave test for the various CPUs.
