Yes, I can confirm that the test compiles OK with recent:

After be977db17c91ad6627dee70a1904a95d229aa1be I don't see this ICE any longer
on either x64 or mips bootstrap.

There is nothing wrong with the constrints in *andndi3_doubleword_bmi:

(define_insn_and_split "*andn3_doubleword_bmi"
  [(set (match_operand: 0 "register_operand" "=,r,r")
(and:
  (not: (match_operand: 1 "register_operand" "r,0,r"))
  (match_operand: 2 "nonimmediate_operand" "ro,ro,0")))
   (clobber (reg:CC FLAGS_REG))]

Reconfirmed as RA problem.
