decode: Remove const fields from decode_rom_t

Browse Source 
The const* fields of decode_rom_t drove multiplexers in decode2 that
picked out various instruction fields and put them into the const*
fields of the Decode2ToExecute1Type record, from where they were
used in execute1.  However, the code in execute1 can just as easily
use the appropriate fields of the original instruction word, since
that is now available in execute1.  This therefore changes the
code to do that, resulting in smaller decode tables.
