split ID -> Reg,Val
This splits the ID namespace into Reg and Val types, hopefully making it
a little easier to follow what's going on, and if we want, allowing us
to size them differently (e.g. val at i32 or i16, reg at i16 or u8). I
didn't notice any speed change when shrinking either, so I've left them
both at i32 for maximum flexibility.
I played with making these strong typedefs with both structs and enum
classes, but both felt a little awkward. I'm still open to the idea.
