I had originally made the handler function pointers a static internal detail, not accessible to the outside world. I did this because they must be accessed in a thread-safe manner, and the library provides thread-safe getters and setters for these. However I am at least temporarily making them public and giving them the Apple-extension names. In the future these may disappear again, and I think that would probably be a good idea.

Quash a TODO related to catching pointer-to-member. These tests fail on my copy of gcc-4.2. But I believe the tests to be correct (and they pass for libc++abi). I've enquired on the C++ standards mailing list for a clarification in case I'm wrong. So far I've gotten one response that agrees with me.

Removing a TODO: can_catch is fundamentally different than search_above_dst. can_catch is looking for an unamiguous public base class of a specific type, but at any address. search_above_dst is looking for an unambiguous public base class of a specific type, *and* at a specific address. Additionally can_catch is run for all types. search_above_dst is only run on class types. So these are only superficially similar. Not similar enough for resuse, at least without making the code unreadable.

Back the optimization down from -O3 to -Os. I'm getting an unexplained crasher on -O3. I've looked for a libc++abi bug and can't find one. I'm suspecting clang optimizer bug. But I don't have a good test case at the moment. Deferring investigation on this for now as I will soon be developing more and smaller tests.

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 :-)

Add a descriptive name for a constant. Also I'm at least temporarily waging war on throw specs, both old and new style. Except where we have already publicly exposed the throw spec, I'm getting rid of them. They may come back later. But they seem somewhat prone to cyclic dependencies here. The throw spec implies compiler generated code that this library has to jump to during stack unwinding. I'd like to minimize the possiblity that the code used to properly make that jump is itself creating such jumps.
