Title: Gc small fixes/trunk

1. embed `bits` into `heaps_slot`
It is faster a bit and more memory efficient after fork (tested with passenger)
2. remove `heaps_freed`
It seems to be never properly used (I could be mistaken). But it definitely unused now.
(May be add usage for it instead of removing?)
3. Simplify `HEAP_ALIGN*` macro usage for experiments (and for OpenBSD fix)
