AArch64 tests
>From Owen:
<span class="quote">> 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?</span ></pre>
