Both the old and new backend framework now provide a method on TargetIsa to do this.

We need a way to map cranelift registers to DWARF registers.

I think this should be part of RegInfo. LLVM stores this map as an array of register pairs, and performs lookups using lower_bound. I'm not sure if cranelift should do the same, or use an array indexed by RegUnit.

Should we wait until after RegInfo generation is converted from python before doing this?
