[PM] Add the explicit copy, move, swap, and assignment boilerplate

Browse Source 
required by MSVC 2013.

This also makes the repeating pass wrapper assignable. Mildly
unfortunate as it means we can't use a const member for the int, but
that is a really minor invariant to try to preserve at the cost of loss
of regularity of the type. Yet another annoyance of the particular C++
object / move semantic model.
