apply asbool reduction to the onclause in join()
The :func:`.true` and :func:`.false` operators may now be applied as the
"onclause" of a :func:`.sql.join` on a backend that does not support
"native boolean" expressions, e.g. Oracle or SQL Server, and the expression
will render as "1=1" for true and "1=0" false. This is the behavior that
was introduced many years ago in :ticket:`2804` for and/or expressions.
