    c++: duplicate const static members [PR 99283]

    This is the bug that keeps on giving.  Reducing it has been successful
    at hitting other defects. In this case, some more specialization hash
    table fun, plus an issue with reading in a definition of a duplicated
    declaration.  At least I discovered a null context check is no longer
    needed.
