450548e3e2 store difference between ip and bytecode start instead of the 
raw ip, which may overflow the integer range.

56dcf497de various fixes, gc can handle running the whole test suite 
in a loop hundreds of times.  the heuristics for growing
the heap still cause it to grow very slowly over time,
but nonetheless slower than boehm.

the gc_var trace.

39fdd89474 not trying to adjust the heap, just keeping a linked list 
of heap chunks.  expanding the heap thus works now, so i've
removed all the debugging utils from gc.c, except the conservative
checks which are now a config option.

bddbaedfa7 test suite now passes with new gc, even starting 
with a tiny heap and causing multiple allocations.
pointer adjusting after a moved realloc still segfaults.

54baeaca36 don't sweep the free-list elements! 
implementing heap expansion w/ realloc.
realloc is always giving back the same pointer right now,
so pointer adjusting not tested yet.
