Concurrent GC should be stable enough to land enabled on X86_64

This fixes a ton of performance and correctness bugs revealed by getting the concurrent GC to
be stable enough to land enabled.

I had to redo the JSObject::visitChildren concurrency protocol again. This time I think it's
even more correct than ever!

This is an enormous win on JetStream/splay-latency and Octane/SplayLatency. It looks to be
mostly neutral on everything else, though Speedometer is showing statistically weak signs of a
slight regression.

Adds the ability to say:

auto locker = holdLock(any type of lock)

Instead of having to say:

Locker<LockType> locker(locks of type LockType)

I think that we should use "auto locker = holdLock(lock)" as the default way that we acquire
locks unless we need to use a special locker type.

This also adds the ability to safepoint a lock. Safepointing a lock is basically a super fast
way of unlocking it fairly and then immediately relocking it - i.e. letting anyone who is
waiting to run without losing steam of there is noone waiting.
