Personally I have never used `das`/`das1` on any AArch64 port when debugging.  I guess it was somewhat handy when the backend was originally developed.  I would argue that the built-in disassembler of any debugger and `disnm` from `debug.cpp` are good enough, and thus `das`/`das1` can be removed.  What do you think @theRealAph ?
