PR19091: Track whether we're demangling a function template specialization to
...
determine whether we get a mangling for a return type, rather than trying to
figure it out based on whether the mangled name ended with a '>'.

Fix demangling crasher. The crasher involved nested <encoding> involving parameter packs, which exposed a logic bug causing an empty vector<string> to be accessed with back(). In addition to fixing the bug, I've inserted numerous preemptive checks for similar bugs in the hopes that if another bug is uncovered, the bug results in an invalid mangled string instead of a demangler crash. Test suite updated with string that was causing the crash.

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.

I created a random mangled name generator and have thrown about 200 million random strings at the demangler. I succeeded in crashing it twice more and those crashers have been fixed and the test suite updated with the crash cases.

__list::ends_with_template was giving the wrong answer for empty lists. And __parse_unnamed_type_name wasn't properly handling the list of paramters and was not safe against incorrectly mangled lambdas (running past last).

Fixes apple: #12020687 . This was a problem in the demangler with template
...
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.
