Slightly less drastic disabling of statistics.

All statistics code is now subject to a switch at each use site, as opposed to a compile-time constant before. We should veryfy that this does not affect performance. Statistics is a useful ability to have for trouble-shooting compile time speeds on specific code bases. But we should not pay a lot for having it on normal runs.
