cmd/asm: add s390x 'rotate then ... selected bits' instructions
This CL adds the following instructions, useful for shifting/rotating
and masking operations:
* RNSBG - rotate then and selected bits
* ROSBG - rotate then or selected bits
* RXSBG - rotate then exclusive or selected bits
* RISBG - rotate then insert selected bits
It also adds the 'T' (test), 'Z' (zero), 'H' (high), 'L' (low) and
'N' (no test) variants of these instructions as appropriate.
Operands are ordered as: I₃, I₄, I₅, R₂, R₁.
Key: I₃=start, I₄=end, I₅=amount, R₂=source, R₁=destination
