Howard Hinnant 86b4dfac01 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.

Howard Hinnant 7530f19d03 Add a few TODO's and FIXME's. Making notes as I go along, but not slowing down to fix these yet. Just don't want anything to fall through the cracks.

Howard Hinnant 5dc3179e5d 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.

Howard Hinnant d3dba31762 __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.

Howard Hinnant dfb34fcb1a 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.

Howard Hinnant 2642af9e23 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.
