 // REGLISTn is a family of macros that we use to define register aliasing.  "n"
 // indicates how many register aliases are being provided to the macro.  It
 // assumes the parameters are register names declared in the "ns"
 // namespace/class, but with the common "Reg_" prefix removed for brevity.
