Thanks HJ for looking into this. I think revision 143027 is not the cause,
it's more likely that it uncovers a latent bug. I'm trying to reduce Joost's
code to a small test case. So far, what I'm seeing is that INSN_CODE is wrong
on the insn that causes the ICE. So some pass is not properly re-recognizing
an insn. The ICE Joost is seeing is happening in lower_subreg2.
My test case (reduced with delta) ICEs with in IRA's record_operand_cost
because extract_insn is filling recog_data.operands with the wrong information.
I'll accept this for now, while I'm investigating.
