Process where clause and joins before opening loops
...
This is background restructuring work to enable us to change the
loop order (or change the way a given loop is handled) based on
what the WHERE and JOIN clauses contain.
Changes:
- `process_where()` called before opening table loops
- Due to the above, `WhereTerm` now refers to table identifiers instead of
cursor IDs because the cursors have not been allocated yet at that point
- `ProcessedWhereClause` now contains a `loop_order`, which just defaults
to the order in the SQL query for now. In the future the loop order may
change depending on the query.
- `loops` removed from `Select` struct; a `LoopInfo` vector is now returned
from `translate_tables_begin()`
