the "ew=" side, being part of the instruction, we don't want to macro-fy.
however the "8", definitely.  NN means "yes macrofy"

other things:

* vec2/3/4 no... maybe.  a case could be made for vecN
* ew=NN  yes elwidths
* sm=NN dm=NN yes predicate mask sources r3 r10 r31 CR fields all options
* modes: no.
  - no mr
  - no satu/sats
  - etc

err... really that's it.

* elwidths including selelecting "default"
* predicate sources including selecting "all 1s"
* vec2/3/4 maybe, including selecting "no subvec"
