additionally, handle many (not yet all) of the keywords used by amd64 words
this exposed an existing flaw in the metadata entry processing, which is now fixed as well. to wit: it's common for provide-substring entries to come after the comment entries they go with in the entry array, but this is valid because adjust-length commands can edit the length field of the comment entry afterwards, and the comment entry will be moved to after the provide-substring entry based on its final length, but this can't happen if the adjust-length array isn't able to find the comment entry it goes with, which may not be the most recent entry. so, the adjust-length command needs to scan backwards to find the most recent comment entry, not just the most recent entry.
confused? don't worry... this CL includes documentation. wow. that was a lot.

this worked by coincidence since it's only ever called in one place, to encode :eax, whose encoding happens to be 0. oops.
thanks to @atax1a@infosec.exchange for spotting this

so it's all just high-level flow control now, which makes it load in itself
the output isn't identical on the first self-compilation, but it converges on the second
with this, it is officially self-hosting. WOW.

so okay, now all the machine code stuff is implemented and it builds without crashing
the generated executable still crashes though, but this was enough work that it's getting a celebratory check-in
