Geoff Berry b1e8714af9 [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.

README 

This directory contains tests for the MIR file format parser and printer. It
was necessary to split the tests across different targets as no single target
covers all features available in machine IR.

Tests for codegen passes should NOT be here but in test/CodeGen/sometarget. As
a rule of thumb this directory should only contain tests using
'llc -run-pass none'.
