This isn't something that should be fixed in the back-end, but most likely an
enhancement to a pass such as ifcvt. To handle this case we would have to
teach ifcvt about dominated conditions and conditional comparisons -- at
present it can only handle conditional insns that do not modify the predicating
condition.
