... and that would be because I changed the operand patterns in
zeroextractsi_compare0_scratch and didn't restore the originals when
trying the new diff :/

So the diff I posted last night might do the trick.
If there's no obvious reason why it would be wrong, I'll start a
bootstrap and regression test tonight.
