It should be easier to iterate a Vector backwards

[Sam Weinig]

The current method of iterating Vectors backwards is a bit ugly and doesn't work with C++11 range-based for loops.  I want an easier way!

Please explain why we set GTEST_HAS_TR1_TUPLE to 0 here.

Typo, reveresed. Also, this isn't true. You could do something like

for (Vector<int>::const_iterator it = intVector.reversed.begin(), end = intVector.reversed.end(); it != end; ++it) { }

Ok.

Doh. I will change to test that way. weinig--.

[Sam Weinig]

Actually, if I don't need to use auto, I don't really need to change TestWebKitAPI to use C++11, but that might be nice on its own since then we could add tests for the rvalue stuff I added to RetainPtr and friends.

Thoughts? Do all the bots have new enough clang/libc++ for this not to break stuff?
