  Log Message:
  -----------
  [ARM][MVE] Refactor option -disable-mve-tail-predication

This refactors option -disable-mve-tail-predication to take different arguments
so that we have 1 option to control tail-predication rather than several
different ones.

This is also a prep step for D82953, in which we want to reject reductions
unless that is requested with this option.
