vm: on 32-bit, the largest free block size was only 512mb, leading to weird errors if the heap grew beyond this. eliminate this limit

vm: various minor optimizations speeding up gc0 and dispatch1 benchmarks, as well as bootstrap
...
- make allot_object() inline, move slow case to allot_large_object()
- reduce number of conditional branches in megamorphic cache miss handler
- make unbox_array_size() inline, move slow case to unbox_array_size_slow()
- new memset_cell() function uses memset_pattern4/8() on Mac OS X

vm: during tenuring stage of aging collection, if tenured space fills up, it would attempt a to_tenured collection. this will succeed if all roots were tenured. however, this is unsound, because there's now an untraced segment of tenured space. fix: if tenuring fails, go on to do a full collection instead
