    Darwin: Amend linker-visibility of strings [PR126723].

    There seems to be quite some variability in the cases that clang makes
    string constant labels linker-visible, however the most conservative
    case is "all of them" which appears to be the strategy for aarch64.
    We dadopt this here, although there is some slight loss of efficiency
    for x86_64.

            PR target/126723

    gcc/ChangeLog:

            * config/darwin.cc (darwin_encode_section_info): Make all
            string constant labels linker-visible.  Likewise const
            section anchors.
