Migrate configs for the Gigabyte Socket 4/5 machines ( #4111 )
...
* Bring back machine migration
And add migration for the Gigabyte Socket 4 and 5 machines
* Fix the GA-586IS's internal name

Since backward compatibility with pre-build 2654 configs has been
removed, remove forward compatibility with these builds as well

Split the 286/386 interpreter away from the 486+ one (the 286/386 interpreter does not use the pccache's, readlookup's, and writelookup's as the emulated CPU's are too slow for them to be required, and also has more accurate FPU timings), also added a LPT status read function for future-proofing.
