[PATCH] [AArch64][ARM] Match interleaved memory accesses into ldN/stN/vldN/vstN intrinsics.

[Hao Liu]

Hi rengolin, mzolotukhin, jmolloy, silviu.baranga,

Hi,

I refactored the patch in D10335 according to the comments. The main concern is to share as much code as possible.

This patch adds a new pass called InterleavedAccessPass in the lib/CodeGen. It constains the code about identifying interleaved accesses. As we can not share the code about creating target specific intrinsics, I put such code in the target backends.

Review please.

Thanks,
-Hao
