68030:
- on write/rwm faults WinUAE throws the exception at the instruction which causes the fault (2,a7) instead of the next instruction which is reported on a real 68030, this is only a difference to the real hw, WHDLoad has not a problem with that because it doesn't use the reported pc for anything (check #3202-3, wrong message)

I did some real 68030 testing with enforcer and it seems (most?) instructions that end in write to memory have bus error stack frame PC pointing to following instruction. Even MOVEM to memory does it.
I'll probably emulate this after 4.1.0 is out.
