The third patch provides a correct declaration of the z10 pipeline

instructions were generated by an insn named *insv<mode>_reg_extimm. The
easiest way to achieve this was splitting the insn into two separate
insns which also simplifies a condition. Bootstraps and does not
introduce new test case failures.
Mmmh not sure about that one. I would prefer to keep it as a single
