Improve and generalize rotate patterns. Rotates by more than half the
bitwidth of a register are canonicalized to rotate left. Many existing
shift patterns don't handle this case correctly, so add rotate left to
the shift iterator and convert rotate left into ror during assembly
output. Add missing
