    Specialize value_cast error message for Ada
    
    In Ada, the term for a cast is "type conversion".  AdaCore has been
    carrying a local patch to specialize the error message in value_cast,
    but it seemed fine to me for this to be part of gdb.  This also
    removes a dead "return" statement.
