Subject: params: Convert the CPU objects to use the auto generated param
 structs. A whole bunch of stuff has been converted to use the new params
 stuff, but the CPU wasn't one of them.  While we're at it, make some things a
 bit more stylish. Most of the work was done by Gabe, I just cleaned stuff up
 a bit more at the end.
