vm: Introduce vm_nr_threads_running()
We need to keep track of running threads when stopping the world. This
means that we must exclude threads that are waiting on monitor. This
patch introduces a vm_nr_threads_running() that will be used in vm/gc.c.

gc: Fix safepoints when gc_start() is called from object allocator
This fixes various of deadlocks and race conditions in gc_start() when
called from object allocator:
(1) Don't deadlock during early bootstrap when there are no running
threads.
(2) Use vm_nr_threads_running() that accurately keeps track of
running threads so that we don't deadlock on a thread that waits
on a monitor.
(3) Make gc_start() re-entrant while waiting for threads to arrive
at a safepoint by turning gc_start() into a safepoint.
(4) Make sure all threads exit their safepoint before letting a thread
stop the world.

gc: Introduce gc_malloc() entry-point
This patch introduces a gc_malloc() entry point. It's a simple wrapper
on top of kzalloc() for now.
