For now simply call into the runtime at the places where the registers are lacking. `quick_enter` should take care of the cases where we otherwise would have skipped calling into the runtime, as x86_32 calls into the runtime regardless (to get the thread) this may even be performance neutral.

Nice! Looks reasonable. Yeah I've been thinking the same: if we need to call runtime to fetch the Thread* anyway, we might as well do all the locking stuff there.
