tip-of-trunk clang has corrected some access checks for special members in a virtual inheritance hierarchy. Change a few private inheritances to protected. This change will not impact what the test was testing. This fixes http://llvm.org/bugs/show_bug.cgi?id=16753 .

I'd no sooner made the last commit when Matthew Dempsky sent me another test case that led me to yet another closely related test case that the current design could not handle. I've now changed the way forward references are handled completely. It wasn't that much code to change. The demangler, when confronted with a forward reference to a template parameter, now parses things twice. During the second parse, all forward references are remembered from the first parse. Test suite updated with new case.

After a private conversation with Arthur O'Dwyer, and a good night's sleep, I believe this fix is a better fix than what I committed in r184656 yesterday. I've basically moved the checking for '`' from the start of the demangling process to the end of it. In the process I discovered that one of the test cases no longer demangled to the expected string. After further investigation I believe this case to not be a valid mangled string, and so I moved the test case to the 'invalid cases'. The reason I believe it is invalid is that it should use T_ instead of T0_ to index the template parameter.

substitution forward references. That is, sometimes a mangled name refers to
a substitution that hasn't yet been defined. The demangler was derferencing a
null pointer in this case because it wasn't properly guarded against a
forward reference. Test case added to catch this problem.

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.

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.
