Make _Unwind_Backtrace() work on ARM.
...
Summary: Since the personality functions do the actual unwinding on ARM,
and will also stop unwinding when they encounter a handler, we invoke
_Unwind_VRS_Interpret() directly form _Unwind_Backtrace().
To simplify, the logic for decoding an EHT is moved out of
unwindOneFrame() and into its own function, decode_eht_entry(). Unlike
unwindOneFrame(), which could only handle ARM's compact personality
function entries (section 6.3) decode_eht_entry() can handle the generic
entries (section 6.2).

Add lit configs for libcxxabi tests.
...
This makes running libcxxabi tests on Linux _much_ easier.
Adds a check-libcxxabi target to cmake.
Also defaults to building a dynamic libc++abi. This is so that the
default options still test the libc++abi that is being built. There are
two problems with testing a static libc++abi. In the case of a
standalone build, the tests will link the system's libc++, which might
not have been built against our libc++abi. In the case of an in tree
build, libc++ will prefer a dynamic libc++abi from the system over a
static libc++abi from the output directory.

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.

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.
