sorry, CompLogicalOpSubset.  unless carry-in, sticky overflow etc are
needed, which i don't think they are.

each subset grabs only the fields from the instruction decode
(Decode2Execute1Type) that the pipeline actually needs.

that subset is supposed to be dropped into ctx.op, see IntegerData class.
all ospec and ispec classes derive from IntegerData at the moment.
