--- Comment #1 from Uro=C5=A1 Bizjak <ubizjak at gmail dot com> ---
Ho-hum - this was my patch that removed constraint from const_int predicate=
s.
We are talking about:

(define_insn_and_split "*anddi_1_btr"
  [(set (match_operand:DI 0 "nonimmediate_operand" "=3Drm")
        (and:DI
         (match_operand:DI 1 "nonimmediate_operand" "%0")
         (match_operand:DI 2 "const_int_operand")))
   (clobber (reg:CC FLAGS_REG))]

Apparently, the assumption that const_int predicates do not need cosntraints
does not hold.=
