After a few false starts, I came up with the patch below, which keeps
track of not just the candidate insn, but also an activation insn, and
chooses candidates only if they are both available and active. Besides
passing a new arg to create_cand, the changes in create_cands are
mostly cosmetic to make the function less confusing. This was
bootstrapped and tested on x86_64-linux. Ok?

The patch looks ok for me.  Thanks for working on the PR, Bernd.

I should get in the habit of asking "ok everywhere?" Can I put this ongcc-5-branch as well?
