From: Sven Verdoolaege <sv...@cerebras.net>

In the bindings, it can be more convenient to use a method
on the domain of the object than
to call a named constructor with the set as argument.

The naming is analogous to isl_space_param_aff_on_domain_id,
which ensures that the new function is also exported
to the templated interface.

As a convenience, a piecewise multiple expression can
also be created from a piecewise expression.
