The changes in src/exception.cpp and cmake/Modules/HandleLibCXXABI.cmake fix a
bug when building libc++ with GCC. Because GCC does not support __has_include
we need to explicitly tell it that we are building against libc++abi via the
preprocessor definition `LIBCXX_BUILDING_LIBCXXABI`.
The changes in include/ratio are to work around CWG defect
1712 (constexpr variable template declarations). GCC 4.8 and before has not
adopted the resolution to this defect.
The changes in include/exception work around an issue where is_final is used
without it being defined in type_traits.

Summary:
This patch does 2 main things:
1. Enable sized delete if the feature test macro `__cpp_sized_deallocation` is enabled.
2. Rework and cleanup all of the sized delete tests.
Test Plan:
The sized delete replacement tests are now split into 4 files:
1. sized_delete11.pass.cpp: Ensure overriding sized delete in C++11 has no effect.
2. sized_delete14.pass.cpp: Test overriding sized delete in C++14 and ensure it is called. This test fails on clang and GCC < 5.1.
3. size_delete_calls_unsized_delete_.pass.cpp: Test that the default sized delete calls unsized delete.
4. sized_delete_fsizeddeallocation.pass.cpp: Test overriding sized delete when -fsized-deallocation is passed. This test should pass on clang and GCC >= 5.1
I have also removed a lot of cruft from the old tests. They no longer replace the new handler and tests that it is called for bad allocations.

Print both the compiler command and linker command so that it will be
easier for developers to reproduce the failed test cases.

The previous commit breaks the builds when libc++abi is not built with
libunwind becuase the default value for LIBCXXABI_USE_LLVM_UNWINDER is
OFF, which is not pythonized.
This CL fix the problem by calling pythonize_bool().

The test cases were crashing due to the mixed usage of the unwinding
functions from both libunwind and libgcc_s. The unwind functions are
mixed because the "llvm_unwinder" entry is not available in the
lit.site.cfg for libc++. As a result, "-lgcc_s" is picked instead of
"-lunwind". The extra option to lit --param=link_flags="-lunwind" won't
help either.
This CL fix the problem by adding llvm_unwinder to lit.site.cfg.in.

The system_clock::now() function currently uses gettimeofday(). The
problem with gettimeofday() is that it is an obsolete XSI function,
hence unavailable on CloudABI. See:
http://pubs.opengroup.org/onlinepubs/9699919799/functions/gettimeofday.html
Change this code to use clock_gettime() with CLOCK_REALTIME instead,
which is more consistent, as clock_gettime() is already used for
steady_clock.
A previous version of this change actually attempted to change
system_clock::duration, but I reverted this part as it breaks the
existing ABI.
