[SimplifyCFG] Preserve !llvm.mem.parallel_loop_access when merging

When SimplifyCFG merges identical instructions from both sides of a diamond, it
can preserve !llvm.mem.parallel_loop_access (as it does with most of the other
metadata). There's no real data or control dependency change in this case.
