Rework fast/slow path alloc API
...
This lets users do gc_allocate_fast() and know that if they got a
non-NULL result, we could allocate without GC, and so no object was
moved.

Rework options interface
...
Users will want to set options from an environment variable or something
like that. Particular GC implementations will want to expose an
expanded set of options. For these reasons we make the options
interface a bit more generalized and include parsing.

Add ephemeron implementation
...
This commit adds support for ephemerons to the API and wires it into the
collectors. It also adds a new test.

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.

Add conservative heap tracing (not just roots)
...
Also accelerate mark_space_live_object_granules.

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

Add conservative stack capture

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

Fix race condition in computation of mark-while-stopping
...
Choose the ragged stop strategy when the GC kind is determined, so that
we do so with respect to a single measurement of pending unavailable
bytes.
Also remove assert in heap_should_mark_while_stopping, as it can be
called after stopping too, when evacuation is enabled.

Rework pinning, prepare for conservative tracing
...
We don't need a pin bit: we just need to mark pinned objects before
evacuation starts. This way we can remove the stopping / marking race
so that we can always mark while stopping.
