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.

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`.

Summary: ASAN fires on these tests because they don't clean up their memory.

_Unwind_Backtrace is not clearly defined in EHABI and needs more
testing. A bug was created with some initial investigation done
http://llvm.org/PR21444. This test fails with both libunwind and libgcc_s.

Although the current method is valid up till python 3.3 (which is not supported)
this seems to be a clearer way of checking for linux and moves the tests towards
python 3 compatibility.

Summary: Add support for LLVM_USE_SANITIZER to the libc++abi tests. Currently, if libc++abi is configured with LLVM_USE_SANITIZER then none of the tests will pass.

Also remove the audotedection part so that if you're crazy enough to want a
single-threaded abi library, you'll say so explicitly in the build.

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).

Note: The unwinder currently only works on Darwin and on ARM Linux.
Non-ARM Linux support is not yet implemented, and will fail to build.

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.

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 '>'.

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.
