Simplify LIMIT 0 handling in translate_select()

It's a special-case so let's make it special like SQLite does.
Simplifies the logic in `translate_select()` quite a bit.

core: apply Real affinity on columns stored as int
...
Values in sqlite3, as expected, can be stored in different formats to
optimize disk usage. In this case, a 79.0 float will be transformed to a
u8.
sqlite3 deals with this by adding a RealAffinity op after each column
that might need it. Therefore, in this pr we do exactly that :).

We can use Select to keep track of loops and stuff. Having a separate
SelectContext just means we need to pass around more objects to
functions.
