f5e5428d45 Merge 'Syntactic improvements' from Jorge López Tello 
This is a purely syntactic PR. It doesn't change behavior, just rewrites
some loops and removes unneeded parts, like lifetime annotations and
references. Mainly because the Clippy and IDE warnings get annoying.
Don't worry about the number of commits, I just separated based on type
of change.

Closes #732

cb5d86ed8e core/translate: Move prepare_select_plan() to select.rs 
The planner.rs file is pretty big. Let's make it smaller by moving more
of select handling to select.rs.

a700d70281 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()`
