Then we have three problematic patterns and the easiest way to handle it is to
get rid of ix86_bnd_prefixed_insn_p call in length computation for them. I
think the easiest way to do it is to have separate bnd and nobnd patterns for
these instructions. Attached patch helps me to resolve valgrind error. Is
such approach fine?
