This patch adds the assembly/disassembly for the following instructions:

MOVA (array to vector, four registers): Move four ZA single-vector groups to four vector registers.

  (array to vector, two registers): Move two ZA single-vector groups to two vector registers.
  (tile to vector, four registers): Move four ZA tile slices to four vector registers.
  (tile to vector, single): Move ZA tile slice to vector register.
  (tile to vector, two registers): Move two ZA tile slices to two vector registers.
  (vector to array, four registers): Move four vector registers to four ZA single-vector groups.
  (vector to array, two registers): Move two vector registers to two ZA single-vector groups.
  (vector to tile, four registers): Move four vector registers to four ZA tile slices.
  (vector to tile, single): Move vector register to ZA tile slice.
  (vector to tile, two registers): Move two vector registers to two ZA tile slices.
