    testsuite, c++: Account for missing stong symbol aliases.
    
    Darwin does not have strong symbol aliases and therefore must emit complete
    constructors (which might, or might not call others).  Several tests assume
    that a base constructor is emitted (which is fine for targets with strong
    symbol aliases that emit the complete constructor symbol as an alias to the
    base etc.).
    
    Handle the two cases with separate matches.
    
    gcc/testsuite/ChangeLog:
    
            * g++.dg/modules/clone-4_b.C: Account for missing strong symbol
            aliases.
            * g++.dg/template/explicit-instantiation8.C: Likewise.
