ir3: convert shift amount to 16b for 16b shifts

NIR has shifts defined as:
 opcode("*shr", 0, tuint, [0, 0], [tuint, tuint32], False, ...

However, in ir3 we have to ensure that both operators of shift
instruction have the same bitness.

Let's hope that in future the additional COV for constants would
be optimized away.
