<summary>Changes</summary>
These stats are added or changed:
1. In summary:
1. Add `totalSymbolsLoaded`. The total number of symbols loaded in all
modules.
2. Add `totalSymbolTablesLoaded `. The total number symbol tables loaded in
all modules.
2. In each module's stats:
1. Add `symbolsLoaded`. The number of symbols loaded in the current module.

Still running tests. Will update here.
