Issue #199 - More efficient memory usage
...
Only use a single int on the heap to store the number of huge heap allocations. There is no need to track allocations on the other heaps, at least at this time.

Issue #199 - Initiate GC using huge GC alloc count
...
Free space does not work for huge heaps since often they are allocated on demand as a full page at a time. But if more than X huge pages have been allocated, it is probably a good time to initiate a major GC.

Mark objects when collector cooperates
...
When the collector cooperates for a mutator it needs to mark any heap-collected objects that are stored within the mutator's data object. This prevents problems where these objects (which are essentially per-thread global roots) are incorrectly collected.

GC tweaks to avoid free/grow thrashing
...
Attempt to prevent thrashing the GC during earley benchmark by:
- Allowing a larger max page size
- Only freeing huge pages. This prevents thrashing where pages are freed only to be immediately reallocated when the heap is grown after sweep.
Longer term it may be necessary to allow freeing of pages by being more intelligent about things.

Potential speedup?
...
Attempt to speed up gc_collector_mark_gray by forcing it to be inlined via a C macro. I am skeptical the compiler cannot do this already but the change seems to speed the earley benchmark up by several seconds.

GC performance improvements
...
- Increase page size
- Cache last page that had an allocation, and start from that page next time, if possible. This speeds up allocation on large heaps because we can avoid searching through the whole heap each time.
