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

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.
