Move wide with zero moves an optionally-shifted 16-bit immediate value to a register.
This instruction is used by the alias MOV (wide immediate).

| <Wd> |
Is the 32-bit name of the general-purpose destination register, encoded in the "Rd" field. |
| <Xd> |
Is the 64-bit name of the general-purpose destination register, encoded in the "Rd" field. |
| <imm> |
Is the 16-bit unsigned immediate, in the range 0 to 65535, encoded in the "imm16" field. |
| Alias | Is preferred when |
