To provide mapping between standard and microMIPS R6 variants of the `sw` command we have to rename SWSP_xxx commands from "sw" to "swsp". Otherwise `tablegen` starts to show the error `Multiple matches found for `SW'`. After that to restore printing SWSP command as `sw`, I add an appropriate `MipsInstAlias` instance. We also need to implement "size reduction" for microMIPS R6. But this task is for separate patch. After that the `micromips-lwsp-swsp.ll` test case will be extended.
