Refactor embedder interface for conservative GC
...
Now users don't have to #ifdef on conservative vs precise tracing; it's
just a generic embedder concern.

...
This isn't really wired up yet anywhere, but add a precursor to
conservative stack scanning.

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.

Always add a header onto objects
...
We're targetting systems that need to be able to inspect the kind of an
object, so this information has to be somewhere. If it's out-of-line,
we might save memory, but we would lose locality. Concretely in Guile
the tag bits are in the object itself.

Update barrier functions to also have the object being written

Also remove read barriers, as they were unused, and we have no plans to
use them.

Add quads benchmark

Also expand GC interface with "allocate_pointerless". Limit lazy
sweeping to the allocation size that is causing the sweep, without
adding to fragmentation.
