Fix SmallPtrSet::iterator behaviour and creation ReverseIterate is true.
- Any function that creates an iterator now uses
SmallPtrSet::makeIterator, which creates an iterator that
dereferences to the given pointer.
- In reverse-iterate mode, initialze iterator::End with "CurArray"
instead of EndPointer.
- In reverse-iterate mode, the current node is iterator::Buffer[-1].
iterator::operator* and SmallPtrSet::makeIterator are the only ones
that need to know.
- Fix the assertions for reverse-iterate mode.
This fixes the tests Danny B added in r297182, and adds a couple of
others to confirm that dereferencing does the right thing, regardless of
how the iterator was found, and that iteration works correctly from each
return from find.

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.

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.

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.

This reverts commit 617330909f0c26a3f2ab8601a029b9bdca48aa61.
It broke the bots:

Value of: v[i].getValue()
Actual: 0

This currently assumes that both sets have the same SmallSize to keep the implementation simple,
a limitation that can be lifted if someone cares.
