Unordered: Test number of copies and moves for moves on all compilers.

Browse Source 
Mainly because I want to get more info on the odd test failure for Visual C++
11. I expect that with move emulation these results could vary considerably,
and since I've only tested with gcc and clang so far, it's quite likely that
this test will now fail for other compilers.
