This is a new unrelated error caused by r160458. You should IMO have opened a
new PR for it. Anyway, the patch below should fix it. Tested in a cross so
far, I'll do a native bootstrap of 4.6 head + this tomorrow. The declaration
bug for 'vec' is obvious. The fact that 'op1' is extracted but unused makes me
a bit nervous.
