Threads just starting up or shutting down might not have any managed
stack frames, leading to a NULL "currFrame" frame pointer in the
interpreter stack.

// state THREAD_SUSPENDED if they're calling back into the VM, or THREAD_MONITOR
// if they're blocked on a monitor, or one of the thread-startup states if
// it's early enough in their life cycle (http://b/7432159).
