Douglas Gregor 3f9047e321 Add a test for "perfect" forwarding

Douglas Gregor f282a76fab Implement the preference for move-construction over copy-construction 
when returning an NRVO candidate expression. For example, this
properly picks the move constructor when dealing with code such as

  MoveOnlyType f() { MoveOnlyType mot; return mot; }

The previously-XFAIL'd rvalue-references test case now works, and has
been moved into the appropriate paragraph-specific test case.

Douglas Gregor bf2f961a35 Add unique_ptr example to test the use of rvalue references. I'll grow 
this example further as more rvalue-reference features come online.
