  Log Message:
  -----------
  [AArch64] Lower SETLE and SETLT vector CondCodes to FCMGT/FCMGE directly.

We previously checked that the compare was NoNan, but the "don't care"
condition codes can be set from known-values as well as nnan instructions.
Lower the vector condition codes directly so that they do not get scalarized
into many scalar instructions.
