  -----------
  [Target][ARM] Change VPTMaskValues to the correct encoding

VPTMaskValue was using the "instruction" encoding to represent the masks
(= the same encoding as the one used by the instructions in an object file),
but it is only used to build MCOperands, so it should use the MCOperand
encoding of the masks, which is slightly different.

  [Target][ARM] Improvements to the VPT Block Insertion Pass

This allows the MVE VPT Block insertion pass to remove VPNOTs in
order to create more complex VPT blocks such as TE, TEET, TETE, etc.
