Misc statistics cleanup; improved merge cost estimations during backpressure.

Misc statistics cleanups include:
- fixes for corner case where c0 is empty, and it would divide by zero
- always compute number of tuples (in / out, but not base)
- rework amount of memory allocated when --test and --newserver are passed in.
