Arthur O'Dwyer 466df1718e [libc++] Update generate_feature_test_macro_components.py to match SD-6.
It's still a little confusing because in many cases C++17 and C++20
have different values, and libc++ implements the C++17 behavior but
not the C++20 behavior; 'unimplemented' can't represent that scenario.
Ultimately we probably ought to completely redesign the script to be
in terms of paper numbers, rather than language revisions, and make
it generate the CSV files like "Cxx2aStatusPaperStatus.csv" as well.

Most newly added macros are unimplemented. I've marked a few as implemented,
though, based on my reading of the code; for example I was pretty sure
`__cpp_lib_latch` is implemented since we have `<latch>`.

libc++ Documentation
====================

The libc++ documentation is written using the Sphinx documentation generator. It is
currently tested with Sphinx 1.1.3.

To build the documents into html configure libc++ with the following cmake options:

  * -DLLVM_ENABLE_SPHINX=ON
  * -DLIBCXX_INCLUDE_DOCS=ON

After configuring libc++ with these options the make rule `docs-libcxx-html`
should be available.
