[PATCH] D14489: [AArch64] Applying load pair optimization for volatile load/store

[Chad Rosier via llvm-commits]

I also wanted to point out that this patch is awesome in that it also allows instructions whos MMOs have been dropped to be merged (hasOrderedMemoryRef makes a conservative assumption when MMOs are missing).  Therefore, this solution will transform more that just volatile loads/stores.  Of course the correct fix is to probably not drop MMO (as is don't in tail merging)...
