add behavior information for x86_64 instructions
this is a squash of a few months' hacking, including but not limited to
what eventually got extracted into
https://git.iximeow.net/asmlinator/about/
the path here is generally not historically interesting, and the vast
majority of this diff is very particular static data tables
(BehaviorDigests and implicit operand lists)
`src/long_mode/behavior.rs` will more or less be directly adapted into
versions for x86-32 and x86-16, similar to the instruction decoders.
