So you mean, add a new keyword (say, "ieee") to dg-effective-target that means "run this test only on ieee targets"?

Another approach might be to have dg-add-options ieee mean what it does today, but also have it skip the test for non-ieee capable targets.  Or is that undesirable because it muddles the meaning of the dg-add-options keyword?  I figure it would make sense because any test that has dg-add-options ieee by definition should be skipped by any target that can't do ieee at all.
