Louis Dionne ba71bd7c55 [libc++] Add the _LIBCPP_HIDE_FROM_ABI_AFTER_V1 macro 
Summary:
This macro allows hiding symbols from the ABI when the library is built
with an ABI version after ABI v1, which is currently the only stable ABI.
This commit defines `_LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY` to be
`_LIBCPP_HIDE_FROM_ABI_AFTER_V1`, meaning that symbols that were only
exported by the library for historical reasons are not exported anymore
in the unstable ABI.

Because of that, this commit is an ABI break for ABI v2. This ABI version
is not stable, however, so this should not be a problem.

README.TXT 

This directory contains abi lists representing the symbols exported
by the libc++ library. The lists are generated using sym_extract.py.

Every time a symbol is added or removed from the libc++ library each of the
lists *MUST* be updated to reflect the changes.

TODO Add more documentation about generating and using the lists.
TODO Add more documentation about the build configuration the lists are generated against.
