target/s390x: addressing exceptions are suppressing
We have to make the address in the old PSW point at the next
instruction, as addressing exceptions are suppressing and not
nullifying.
I assume that there are a lot of other broken cases (as most instructions
we care about are suppressing) - all trigger_pgm_exception() specifying
and explicit number or ILEN_LATER look suspicious, however this is another
story that might require bigger changes (and I have to understand when
the address might already have been incremented first).
This is needed to make an upcoming kvm-unit-test work.
