41591d8722 bdw: Ensure heap and mutators are live 
Before, we were relying on the heap and mutators being reachable from
roots.  This is no longer the case.

d0b8f6838d 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.

4cb26e0144 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.

c614c2e40b 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.

d2bde8319f Add conservative stack capture 
This isn't really wired up yet anywhere, but add a precursor to
conservative stack scanning.

data segments.
