Chandler Carruth 002da5db29 [C++11] Switch all uses of the llvm_move macro to use std::move 
directly, and remove the macro.

Chandler Carruth 667363b3e3 [C++11] Remove uses of LLVM_HAS_RVALUE_REFERENCES from the unittests.

Chandler Carruth c74010df48 Make the moved-from SmallPtrSet be a valid, empty, small-state object. 
Enhance the tests to actually require moves in C++11 mode, in addition
to testing the moved-from state. Further enhance the tests to cover
copy-assignment into a moved-from object and moving a large-state
object. (Note that we can't really test small-state vs. large-state as
that isn't an observable property of the API really.) This should finish
addressing review on r195239.

Chandler Carruth 6d888bc0da Add a test for assignment operator behavior which was changed in 
r195239, as well as a comment about the fact that assigning over
a moved-from object was in fact tested. Addresses some of the review
feedback on r195239.

Chandler Carruth 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.

Jean-Luc Duprat 89fe247094 SmallVector and SmallPtrSet allocations now power-of-two aligned. 
This time tested on both OSX and Linux.

Rafael Espindola de65751493 Revert "Fix allocations of SmallVector and SmallPtrSet so they are more prone to" 
This reverts commit 617330909f0c26a3f2ab8601a029b9bdca48aa61.

It broke the bots:

Benjamin Kramer 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.
