           Summary: [ARM] Enhance the load/store optimizer with
                    target-specific alias analysis.

In r237963, I improved the AArch64 load/store optimization pass to use
target-specific alias analysis.  I'm not sure if the ARM backend already This
may be a trivial port to the ARM backend.  Filing in case Matthias, Gerolf, or
someone else would like to investigate.

I believe the IsSafeAndProfitableToMove would be a starting point for the
pre-RA pass.  I'm not sure where it would fit into the post-RA pass as I
haven't really looked.
