55758e9691 Give SmallPtrSet move semantics when we have R-value references. 
Somehow, this ADT got missed which is moderately terrifying considering
the efficiency of move for it.

The code to implement move semantics for it is pretty horrible
currently but was written to reasonably closely match the rest of the
code. Unittests that cover both copying and moving (at a basic level)
added.

e1c34e9f43 SmallPtrSet: Provide a more efficient implementation of swap than the default triple-copy std::swap. 
This currently assumes that both sets have the same SmallSize to keep the implementation simple,
a limitation that can be lifted if someone cares.
