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.
