    Redo libc++ customizations
    
    * Remove osreldate include because _LIBCPP_HAS_NO_GETS has disappeared
    * Instead, add direct major __FreeBSD__ check for using ::gets declaration
    * Mark EINTEGRITY values as FreeBSD customization
    * Reformat _LIBCPP_TYPE_VISIBILITY_DEFAULT customization
