  Log Message:
  -----------
  [ARM] LowoverheadLoops: add an option to disable tail-predication

This might be useful for testing. We already have an option -tail-predication
but that controls the MVETailPredication pass.  This
-arm-loloops-disable-tail-pred is just for disabling it in the LowoverheadLoops
pass.
