Write more runtime tests and fix bugs
This change adds tests for the new memory manager code particularly with
its windows support. Function call tracing now works reliably on Silicon
since our function hooker was missing new Apple self-modifying code APIs

Many tests that were disabled a long time ago on aarch64 are reactivated
by this change, now that arm support is on equal terms with x86. There's
been a lot of places where ftrace could cause deadlocks, which have been
hunted down across all platforms thanks to new tests. A bug in Windows's
kill() function has been identified.
