e3c4285520 Surround any unmangled C++ names in libcxxrt's version map with 'extern
"C++"', otherwise ld refuses to make the symbols global in the final
library.  This causes the __int128-related symbols to go missing when
the library is stripped during installation.

6fc1c2befc Add __int128-related symbols to libcxxrt's version map. Put these into
the same CXXABI verions as recent libstdc++.

Note that __int128 types are only available on arches where long long is
128 bit wide.

b689d9268f libcxxrt: correct mangled "typeinfo name" symbols in Version.map
r260553 added missing C++ typinfos to libcxxrt's version script.
It appears that a number of duplicate mangled symbols were added due to
a cut and paste error. Switch the second instances to _ZTS*,
typeinfo name for *.

Found by lld, which produces an error or warning for duplicate symbols.

bb52ed3249 Add std::uncaught_exceptions() to libcxxrt (C++17, see N4152 and N4259).
This has also been submitted upstream.

e350ac5e37 Add __cxa_deleted_virtual to libcxxrt's version map.
This symbol can sometimes be emitted by clang++, and was not yet
exported from libcxxrt.  Attempt to be compatible with libsupc++ by
using the same CXXABI_1.3.6 symbol version.

ccf9b6362b Add several missing symbols to libcxxrt's symbol version map, and remove
a few duplicates.  This should fix building world with -stdlib=libc++
after r246028.

4792733bb8 Fix some symbol version mismatches between libstdc++ and libsupc++/libcxxrt
that were causing the runtime and STL libraries to see different versions of
various classes and functions when libstdc++ is used as a filter.

Note: This changes the ABI for libcxxrt, but libcxxrt is currently only in
-STABLE for testing and is not used by anything unless explicitly enabled by
the end user.  No default compiler configurations use it.

libc++ will need to be recompiled after this change.  make buildworld will do
this automatically, but make in lib/libc++ will not necessarily work unless the
new libcxxrt is installed first.
