You missed sim/ppc/psim.c:cntrl_c_simulation.  Of course there's also
psim_max_iterations_exceeded, which uses signal -1... let's just ignore
that for the moment...

Other than that, I think it plausibly likely that you got everything. 
Does anyone object to this change?  This has been a long-standing wart.
