    [libc++] Fix link error with _LIBCPP_HIDE_FROM_ABI_PER_TU and std::string

    Summary:
    This is effectively a revert of r344616, which was a partial fix for
    PR38964 (compilation of <string> with GCC in C++03 mode). However, that
    configuration is explicitly not supported anymore and that partial fix
    breaks compilation with Clang when per-TU insulation is provided.
