b60a1636fc Fix the mortality of the world to avoid runaway feedback between the dynamic criterion and the mortality of the arena's top generation as described in <https://info.ravenbrook.com/mail/2018/07/13/19-53-23/0/>.

326a8c6bbd Generation's computed mortality has denominator of condemned memory (not new memory), so use the same denominator when predicting the mortality for a trace. 
Simpler to compute predicted mortality as casualties/condemned instead of 1 - survivors/condemned.

683c79008c Improve performance of mvff in hot builds by: 
1. Using macros to bypass PoolFree and Land* generic functions.
2. Compiling out assertions on functions on the critical paths for manual allocation and freeing.
3. Taking advantage of the fact that splay->updateNode does not change during a splay operation.
