target-s390: Reorg exception handling
Make the user path more like the system path. Prepare for more kinds
of runtime exceptions. Rename ILC to ILEN to make it clear that we
want to pass around a full instruction length, rather than a "code"
that happens to be stored one bit left in a larger field.
