started here:


preliminary output here (pending data structures / types)


it should match precisely with the array lengths from decode1.vhdl, and the
idea is that in decode2.vhdl wherever a decode_rom_t is used then a
corresponding sv_decode_rom_t is also used.

if there is no entry and yet the instruction is SVP64-prefixed then an illegal
instruction exception must be raised.
