Some comments, but mainly I'm just bewildered by tablegen.

Is it worth having a comment on this one?

Can we make WithStride a bool, or is that not supported?

It's sort of a nit, but: I think I see what you're trying to do with the alignment of # under the paren, but it doesn't totally work for me, especially when we add a space *after* the #.

Maybe you could just pull the #s up onto the line above? Then we don't have any of these issues.

Alas, there are no bools in tablegen. I can replace it with 'bit', though.
