    SCCP: Fix ODR issues when compiling with LTO [PR 113054}

    The problem here is that in C++ structs and classes have a
    linkage too so the type vertex is not considered local to
    the TU but will conflict with the globally defined one
    in graphds.h.  The simple way to fix this is to wrap the ones
    defined locally in gimple-ssa-sccopy.cc inside an anonymous namespace
    and they are now considered locally to that TU.

    Committed as obvious after a bootstrap/test on x86_64.

            with an anonymous namespace.
