*scalar extsw/b/h gives one set, mv gives another. src elwidth override and dest elwidth override provide the pack/unpack*.
-implemented by [[sv/mv.vec]] RM Pack/Unpack mode as long as these instructions
-have that RM Mode.
+implemented by Pack/Unpack. [[sv/normal]] arithmetic also has Pack-with-Saturate.
