don't mutate the statement in ORM compile

Fixed issue where using a :class:`_sql.Select` as a subquery in an ORM
context would modify the :class:`_sql.Select` in place to disable
eagerloads on that object, which would then cause that same
:class:`_sql.Select` to not eagerload if it were then re-used in a
top-level execution context.

Fixes: #6378
