target/s390x: Fix PPNO execution with icount
Executing PERFORM RANDOM NUMBER OPERATION makes QEMU exit with "Bad
icount read" when using record/replay. This is caused by
icount_get_raw_locked() if the current instruction is not the last one
in the respective translation block.
For the x86_64's rdrand this is resolved by calling
translator_io_start(). On s390x one uses IF_IO in order to make this
call happen automatically.
