Refactor SetCpStatus into two functions for from-GPU and from-CPU mode rather than a boolean parameter.

This shouldn't affect functionality.  I'm not sure if the breakpoint
distinction is actually necessary (my commit messages from the old
dc-netplay last year claim that breakpoints are broken anyway, but I
don't remember why), but I don't actually need to change this part of
the code (yet), so I'll stick with the trimmings change for now.
