    libitm: small update for C++20
    
    C++20 DR 2237 disallows simple-template-id in cdtors, so you
    can't write
    
        template<typename T>
        struct S {
          S<T>(); // should be S();
        };
    
    This hasn't been a problem until now but I'm adding a warning about it
    to -Wc++20-compat which libitm apparently uses.
    
    libitm/ChangeLog:
    
            * containers.h (vector): Remove the template-id in constructors.
