This is going to break previously working setups involving

To be honest I've never found -exec logging that useful for system
emulation (beyond check-tcg tests) because it just generates so much
data.

It can be very useful for "give me a list of all the
PC values where we executed an instruction", for shorter
test cases. You can then (given several of these) look at
where two runs diverge, and similar things. I use it,
so please don't break it :-)

Ok, I'm reworking the patchset to always have the proper virtual pc for logging.
