I took a look at fr30.cpu.

It seems that `h-r13' is not tied to the general purpose register
bank, though.  So if I use one of these `R13' instructions and then
later use `r13' in an instruction taking a general purpose register
operand, I don't see how I'll get the same register value.  Am I
missing something?
