It is a common trick to return an empty register name for a (raw)
register to hide the register from the user. So I don't think this
diff is ok, since the goal obviously is to hide the raw registers in
mips in favour of the pseudo registers.
I'd say the proper way forward is to teach the trace code to handle
pseudo registers.
