Geoff Berry 7d7873efde [AArch64][Falkor] Avoid HW prefetcher tag collisions (step 1) ...

Summary:
This patch is the first step in reducing HW prefetcher instruction tag
collisions in inner loops for Falkor.  It adds a pass that annotates IR
loads with metadata to indicate that they are known to be strided loads,
and adds a target lowering hook that translates this metadata to a
target-specific MachineMemOperand flag.

A follow on change will use this MachineMemOperand flag to re-write
instructions to reduce tag collisions.
