Mike Bayer d6db28556b Don't cache a query that has before_compile modifications ...

The :class:`.BakedQuery` will not cache a query that was modified by a
:meth:`.QueryEvents.before_compile` event, so that compilation hooks that
may be applying ad-hoc modifications to queries will take effect on each
run.  In particular this is helpful for events that modify queries used in
lazy loading as well as eager loading such as "select in" loading.  In
order to re-enable caching for a query modified by this event, a new
flag ``bake_ok`` is added; see :ref:`baked_with_before_compile` for
details.

A longer term plan to provide a new form of SQL caching should solve this
kind of issue more comprehensively.
