This does not implement all opcodes related to div/sqrt as specified in the xtensa ISA, partly because the official specification is not complete and partly because precise implementation is unnecessarily complex. Instead instructions specific to the div/sqrt sequences are implemented differently, most of them as nops, but the results of div/sqrt sequences is preserved.
