A bug fix involving the updating of path_dst_ptr_to_static_ptr. Some minor code rearrangement optimizations (putting most likely 'if' first in an if-else series. And some major optimizations which involve stopping the search prior to an exhaustive walk over the entire tree. Some of these stops are because an ambiguity is detected earlier. And some of the short circuiting is due to the information from the bits __diamond_shaped_mask and __non_diamond_repeat_mask. The stress test checked in last night is now about 28% faster for the B<Width/2, Depth> -O3 case. I'm still playing with some more optimization possibilities but I'm not sure they will play out.

Put debug print statments under a flag so that I can get a first glimpse at performance. So far I haven't noticed any performance difference between this new __dynamic_cast and gcc's implementation. But I've barely started looking. Also adding a couple of tests which come straight out of the standard.

Fixed a couple of bugs, updated many comments, and am including a comprehensive test for when there are only 3 types in place. I need to do something similar for 4 and maybe more types, but I'm not sure how comprehensive I can make the test at 4 and above types.

Initial implementaiton of __dynamic_cast. There is still lots of debugging code in here that needs to be stripped out. And many, many unit tests need to be written. And comments and probably code cleanliness needs to be improved. But I *think* the basic algorithm is sound. There also may still be some oportunities for algorithm optimization, I'm not positive.

This is a transitory commit for __dynamic_cast. It contains debugging statements that are not intended to be in the finished product. However some of the dubbing statements themselves contain important documentation such as how to navigate a __class_type_info hierarchy, documenting object offset and inheritance access. The intention is that this debugging code will migrate into both actual code and comments. And capturing it here so that there is no chance this stuff will be lost.

First brush with testing __gxx_personality_v0 reveals there is still a long way to go. But my understanding of what it is supposed to do continues to improve. I am currently contemplating whether I need to implement typeinfo before completing __gxx_personality_v0 in order to get matching catch handlers correct.

Correct comment regarding members of __cxa_dependent_exception. Actually it is useful to disguise a __cxa_dependent_exception as a __cxa_exception by filling in most (not all) of these members at __cxa_dependent_exception construction time. That way most routines don't have to care which kind of exception they have.

__gxx_personality_v0 update. This is completely untested code. But my brain is scrambled and I wanted to get it checked in. Code review from anyone who knows anything at all about personality functions would be much appreciated. What is in here is borrowed heavily from llvm/examples/ExceptionDemo/ExceptionDemo.cpp. There are some calls to abort() that should probably be changed to return an error code instead. There may be encodings under readEncodedPointer that need to be implemented. And my handling of type_info is almost a complete guess.

Substituted std::get_terminate() for direct access to the handler function pointer (which is now a static in cxa_handlers.cpp). This has the advantage of going through the atomic API and so is less likely to cause a data race. Ditto for unexpected.

terminate, unexpected and new handlers. If terminating while an exception is unwinding, an attempt is made to print out the what() string if the exception is derived from std::exception. __terminate(handler) and __unexpected(handler) helpers are present in anticipation of other parts of libc++abi needing to call these interfaces with custom handlers.
