Austin Clements b30d19de59 runtime: introduce higher-level GC work abstraction 
This introduces a producer/consumer abstraction for GC work pointers
that internally handles the details of filling, draining, and
shuffling work buffers.

In addition to simplifying the GC code, this should make it easy for
us to change how we use work buffers, including cleaning up how we use
the work.partial queue, reintroducing a FIFO lookahead cache, adding
prefetching, and using dual buffers to avoid flapping.

This commit doesn't change any existing code.  The following commit
will switch the garbage collector from explicit workbuf manipulation
to gcWork.
