Remove embedder requirement for per-object remset bits
...
Since we now have a field-logging write barrier, we don't need
per-object log bits.

Explicitly support immediate values
...
Because we have to deref edges ourselves, as part of generational
marking, we need to ignore edges that don't point to heap objects.

Instead of the card table, use metadata bytes for field-logging. More

Add field-logging write barrier (fast path only)
...
Add a new kind of write barrier, one which has a bit per field; the
mutator that sets the bit will need to add the field's location (the
edge) to a remembered set. Here we just have the fast-path
implementation.

Remove scc
...
PCC with GC_PARALLEL=0 is exactly equivalent to SCC. Also now that PCC
will dynamically avoid atomic forwarding if parallelism is disabled at
run-time, there is no need to keep SCC around.

Reorder events in event listener; refactors to mmc and pcc
...
In GC, request mutators to stop before doing anything else; changes the
order of the event listener interface. Also, refactor mmc to look more
like pcc.
