vec_extractv2sisi is available in mmx.md even with -mno-mmx:

(define_expand "vec_extractv2sisi"
  [(match_operand:SI 0 "register_operand")
   (match_operand:V2SI 1 "register_operand")
   (match_operand 2 "const_int_operand")]
  "TARGET_MMX || TARGET_MMX_WITH_SSE"
{
  ix86_expand_vector_extract (TARGET_MMX_WITH_SSE, operands[0],
                              operands[1], INTVAL (operands[2]));
  DONE;
})=
