CPUClass set_pc() and get_pc() handlers are target specific.
Rather than passing a generic CPUState and forcing QOM casts,
we can directly pass the target CPUArchState, simplifying.

This is effectively the table of methods for the CPUClass
class. I think that methods on class A should take a pointer to the
object of that type, not to something else.

Yeah, the diffstat is enticing but I agree.  It's particularly confusing 
because there isn't a single type called CPUArchState*, it's different 
depending on which target/ subdirectory you're compiling. In a 
multi-target binary it'd have to be void*, and then you get back the casts.
