It's very easy to implement the exact same behavior as gdb_test, but
are we certain that this is a valuable capability?  Looking at the
documentation for that function, one can find:

    # MESSAGE is an optional message to be printed.  If this is
    #   omitted, then the pass/fail messages use the command string as the
    #   message.  (If this is the empty string, then sometimes we don't
    #   call pass or fail at all; I don't understand this at all.)

The current implementation seems inconsistent; but also I don't think
that is really makes that much difference whether the test generates
a result or not.

But if that's what people want...
