Pass heap to tracer functions
...
This will allow conservative intra-heap edges. Hopefully no overhead?

trace_worker_steal first does a try_pop on its own deque
...
Before asking other threads for values, see if there is any pending data
that overflowed from the local mark stack.

work-stealing optimization: stay with last-stolen worker
...
Previously we were always going round-robin. Now a thief tries to
plunder its victim again directly. Should result in less churn.

Fix bug in try_pop on chase-lev deque
...
The counters are unsigned, so that they can overflow. (Is that really
necessary though?) In any case try_pop can decrement a counter, leading
to a situation where you can think you have (size_t)-1 elements; not
good. Instead when computing the queue size, use a signed value.
Limits total queue size to half the unsigned space; fine.

Separate tagging from collector
...
The collector now has an abstract interface onto the embedder. The
embedder has to supply some functionality, such as tracing and
forwarding. This is a pretty big change in terms of lines but it's
supposed to have no functional or performance change.

Rename mark-sweep "markers" to "tracers"

There could be other reasons than marking to trace the heap.
