I should have said that *currently* there is no way to combine them.
We override dg-process-target and can come up with a way to provide
both "target" and "xfail" in the target-selector.  Something like:

  target { selector } xfail { selector }

where "target" is the first argument, "xfail" is the third.
Selectors can be lists of target triplets, but those can be within
braces making them a single argument.  What do you think?
