Changelog:
- Emulator: use `(uintmax)-1 >> 1` for the units of time
- MD: implemented 13 new 68K instructions (basically all of the
remaining easy ones); 21 remain
- nall: replaced `(u)intmax_t` (64-bit) with *actual* `(u)intmax` type
(128-bit where available)
- this extends to everything: atoi, string, etc. You can even
print 128-bit variables if you like
22,552 opcodes still don't exist in the 68K map. Looking like quite a
few entries will be blank once I finish.
