[libcxxabi] Refactor building and testing libc++abi without threads
...
Summary:
This patch adds CMake support for building and testing libc++abi without threads.
1. Add `LIBCXXABI_ENABLE_THREADS` option to CMake.
2. Propagate `LIBCXXABI_ENABLE_THREADS` to lit via lit.site.cfg.in
3. Configure tests for `LIBCXXABI_ENABLE_THREADS=OFF
Currently the test suite does not work when libc++abi is built without threads because that information does not propagate to the test suite.

[libcxxabi] Refactor test timing logic and disable by default.
...
Summary:
When using LIT the timing output is entirely unused but introduces a dependency on `<chrono>`. When libc++ is built without a montonic clock this causes some of the tests to fail.
This patch factors out all of the timing logic into `support/timer.hpp` and disables it by default. To enable the timing you must define `LIBCXXABI_TIME_TESTS`.

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).

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.

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.

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.
