Richard Smith bd32a449e6 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 '>'.

Logan Chien cc24fc546b Check exception specification with __cplusplus.
To allow the compilation with gcc, we can't use the
__has_feature(cxx_noexcept) to detect the default destructor
exception specification, which is noexcept(true) by default
in C++11.  We should use __cplusplus >= 201103L instead.

Howard Hinnant 14fe17f302 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.

Howard Hinnant b162939c1a 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.

Howard Hinnant 60c16eb7f5 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.

Howard Hinnant cde9e006d8 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.

Howard Hinnant 72a54eab35 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.

Howard Hinnant c1c87c15f2 __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).

Howard Hinnant 757640b156 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.

Howard Hinnant b2a9cee678 Erik Olofsson: This patch adds support for lambda demangling. I fixed this because it crashed lldb when it tried to demangle the added test.
Not sure how it should identify the lambda so that might need changing from the current 'lambdax'::  Howard:  Please patch CREDITS.TXT.

Howard Hinnant 2d6810fbd6 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.
