see comment #30, i was expecting it to be a single uint64_t per
instruction - no struct at all - just a series of #defined macros
which extract the relevant bits from the required locations in the
uint64_t.

this is exactly the same technique used elsewhere in binutils.

therefore there should be no struct entries per se - just a list
of #defined entries, followed by ORing them together, and a matching
set of macros to extract the required information.
