The back end enumerates floating point registers a V32-V63, but the instruction generator encodes them as R0-R31. This PR does the conversion in the instruction generator, as it is easier to place correctness checks there rather than scattered through the code generator.
Also started naming the floating point registers with the V prefix rather than the R.
