Export missing symbols. * testsuite/27_io/filesystem/iterators/91067.cc: Test move constructors. * testsuite/util/testsuite_abi.cc: Add new symbol version.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.
