As mentioned yesterday, we need to add some more exports for
std::filesystem directory iterators. As discussed in PR 91067 Clang
inlines the move constructor and optimises it to a tail call to the C2
move constructor of __shared_ptr, which wasn't exported.
Tested x86_64-linux, i686-linux, powerpc64-linux. Committing to trunk
and (later today) gcc-9-branch.
This documents the change, committed to trunk and gcc-9-branch.
