Comment (by luite):

 Changing the argument demand type from `evalDmd` to `topDmd` (in
 `MkId.mkFCallId`) fixes the problem for this test case and for GHCJS, and
 other than a minor (and I think harmless) change in one of the `stranal`
 test cases doesn't cause any validate issues.

 I just want to make sure, is this a sane thing to do?
