Fully copy index expressions
Fixed bug where the :meth:`.Table.tometadata` method would not properly
accommodate :class:`.Index` objects that didn't consist of simple
column expressions, such as indexes against a :func:`.text` construct,
indexes that used SQL expressions or :attr:`.func`, etc. The routine
now copies expressions fully to a new :class:`.Index` object while
substituting all table-bound :class:`.Column` objects for those
of the target table.
Also refined the means by which tometadata() checks if an Index
or UniqueConstraint is generated by a column-level flag, by propagating
an attribute "_column_flag=True" to such indexes/constraints.
