general-purpose Galois Field 2^M operations are added so as to avoid huge custom opcode proliferation across many areas of Computer Science. however for convenience and also to avoid setup costs, some of the more common operations (clmul, crc32) are also added. The expectation is that these operations would all be covered by the same pipeline.
note that there are brownfield spaces below that could incorporate some of the set-before-first and other scalar operations listed in [[sv/vector_ops]], and
-the [[sv/av_opcodes]] as well as [[sv/setvl]]
+the [[sv/av_opcodes]] as well as [[sv/setvl]], [[sv/svstep]], [[sv/remap]]
