The instructions are MOVK(W), MOVZ(W) and MOVN(W), the assembly syntax is "op $(uimm16<<shift), <Rd>". The <uimm16>
is the 16-bit unsigned immediate, in the range 0 to 65535; For the 32-bit variant, the <shift> is 0 or 16, for the
64-bit variant, the <shift> is 0, 16, 32 or 48.

The current Go assembler does not accept zero shifts, such as "op $0, Rd" and "op $(0<<(16|32|48)), Rd" instructions.
