a8bcb796a7 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.

764c0e1235 In mps_arena_roots_walk, don't call traceaddwhite to whiten a segment, as this calls segwhiten which has undesirable side-effects, including breaking formatting objects walking. instead, call segsetwhite to make the segment white, and set the trace's white summary to the universe. 
Add cross-reference from second-stage test in _mps_fix2 so that if the white set test is changed, the roots walking code can be changed to match.
In walkt0, add a smoke test for mps_arena_roots_walk.

5076ca4c04 Fix the check of the cbs overlapping insertion failure case: in order for the inserted block not to overlap it's right neighbour, its limit must be <= the base of the right neighbour (not the limit as previously written). this mistake was introduced accidentally in change 182344.

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.
