Oof. I suppose they're all at least that long, but still - we're looking
only for barriers, right? Might be better to encode this expectation
using an assert, like so:
rtx_code code = GET_CODE (insn);
if (code == BARRIER)
return false;
gcc_assert (GET_RTX_FORMAT (code)[2] == 'B');
Otherwise, nice, and ok.
