If the rotate argument is the constant 0, rlwnm may be generated instead of rlwinm. In all reasonable cases, this is OK as R0 should hold 0. However, this could be problematic in some cases when writing PPC64 assembly. This consolidates the RLWNM and RLWMI optab entries. Invalid RLWMI usage is still rejected, however the error will be be slightly different. The invalid usage will be caught in oprrr instead of oplook.
