AArch64 tests
>From Owen:
> I’m seeing significant compile time problems introduced by this change on
> AArch64, with a worst case example taking >10 minutes to compile. The root
> cause seems to be the IsReachable() calls introduced here - they’re not
> cheap, and they’re being called a lot. Is there some way we can back off or
> limit the number of queries here?
