546eb76861 gc: free empty pages in gc_heap_merge() 
Moving the code from gc_merge_all_heaps to gc_heap_merge removes
special handling of the start of the list and is (hopefully)
easier to read.

Partial work towards addressing issue #534.

20fc3c6646 gc: free unused parts of the heap before merging 
When a thread exits, the heap is merged into the main thread.
Before doing so, free any unused parts of the heap to reduce
memory usage. Attempts to partially address issue #534.

d8aa289af4 gc: add a function to force the collector to run 
This requires adding a "forced" stage for the collector,
which is the initial stage for a forced collection.
Thereafter, the collector continues to the usual stages
of collection.

543ce4f4be Initiate major GC after a huge heap allocation 
This allows us to reclaim the memory faster and keep memory usage lower.

102244be21 Issue #304 - gc_copy_obj must to populate bignums 
Even without bignums in the nursery we still need this code in place since gc_alloc calls it, and otherwise all of the callers would need to ensure bignums are properly initialized. There may be an opportunity here for optimization, but let's make sure everything works first!
