dmgreen added a parent revision: D65103: [ARM] Better patterns for fp <> predicate vectors.

This adds the patterns required to transform xor P0, -1 to a VPNOT. The instruction operands have to change a little for this, adding an in and an out VCCR reg and using a custom DecodeMVEVPNOT for the decode.
