More test cases concentrating on catching class types.

Drop the stress a notch on dynamic_cast_stress.cpp. Otherwise it occasionally causes clang to crash. Put a noexcept(false) on a throwing destructor in test_vector1.cpp. The test now passes for both C++03 and C++11 modes. Add testit script. All tests are now PASSING :-)

One more small optimization: Where possible, for loops that do a search and then try to break out of the loop early, eliminate the attempt to break out of the loop after the last search. And with that, I'm declaring __dynamic_cast done. Though if anyone sees any problems, has suggestions for improvements, or wants to contribute some test cases, that is certainly welcome feedback.

I think this is getting close on __dynamic_cast. There's been quite a bit of code rearrangement, renaming, and better commenting. This exercise has exposed and fixed a few more bugs. I've also added several more tests (there's definitely a need for more tests here).

Enclosed is a stress test for dynamic_cast. It stresses both libc++abi, and clang itself. It creates a ridiculously large class hierarchy using variadic templates. You can specify both the width and depth of the class hierarchy. And you can specify whether the cast is to the actual run time type, or to an intermediate layer in the class. About 1/3 of the time I compile this, it crashes the compiler. There seems to be an uninitialized area of memory, and I'm probably blowing past an assumption on class hierarchy size within clang (and understandably so). I can get it work most of the time with a class hierarchy width of 20 and a depth of 7. I'm making timings with both -O3 and -Os, using both cast to root and cast to intermediate, on both libc++abi, and gcc's dynamic_cast. I've put the results in a comment/table at the bottom of the test.
