I measured gains on both Spec2006 and EEMBC benchmarks, with no regression that was directly related to the CMOV conversion into branch.
The most noticeable improvements (but there are more), measured on Skylake:

  Spec2006
    429.mcf:     +6%
    456.hmmer:   +12%
  
  Telecom
    fbital00:    +30%
