    c++: dependent attribute on parameter [PR97900]

    We were copying attributes from the template to the instantiation without
    considering that they might be dependent.  To make sure that the new parms
    have the appropriate properties for the code pattern, let's just regenerate
    them.

            * pt.c (regenerate_decl_from_template): tsubst_decl
            the parms.
