71d085091d Fully-generalize gc algorithms 
Updated code to support 3 types of heaps, based on size. Need to be able to use the old algorithms to inspect the active size of each heap. We need to collect if one of the sub-heaps is almost full, even if the others are mostly empty.

b18aadb229 Temporarily disable growing heap after GC 
To get this working properly, would need to figure out if any sub-heaps are nearly full. Since we grow these heaps anyway as needed, this code is not strictly required. So diabling for now to get cyclone to build and run again.

23fd4268a3 More conservative locking when collector cooperates 
Try to prevent cases where the mutator and collector are both running minor GC at the same time.

98a18a225a Handle old stack objects on write barrier 
The gc_mut_update write barrier should not assume that the old object is on the heap, lets also gray the old object if it happens to be on the stack. Worst case, we mark an extra object here or there. Best case, may prevent gc_allocated_bytes receiving forward pointers.
