MScratchC doesn't extend mscratch in the SAIL (similarly for SScratchC/sscratch)

MScratchC extends mscratch in the spec
Also SScratchC extends sscratch

this is not yet reflected in the SAIL model.

thanks, note that this also requires a change in the base RISC-V SAIL model to add a hook into accessing xscratchc
