Fix adaption in AnnotatedLabel; repair needless expense in coercion
Fixed regression involving clause adaption of labeled ORM compound
elements, such as single-table inheritance discriminator expressions with
conditionals or CASE expressions, which could cause aliased expressions
such as those used in ORM join / joinedload operations to not be adapted
correctly, such as referring to the wrong table in the ON clause in a join.
This change also improves a performance bump that was located within the
process of invoking :meth:`_sql.Select.join` given an ORM attribute
as a target.
Fixes: #6550
