Daniel, my task was the expansion of these macros, by mips bugzilla report 723.

I believe that adding these as instructions on supported platforms is a whole different thing. For the start, we need information on which architectures these instructions exist and find their encodings. MIPS64 Instructions Set mentions only ROTR and ROTRV, and these two are already implemented.

I believe that this piece of code will not introduce any critical problems on platforms which support ROL/ROR instructions.

I am also preparing similar patch for DROL/DROR macros.
