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.

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.
