Tidy up claimed supported CPUs and OSes.
* Remove arbitrary mention of certain endianness and bitness variants;
it's enough to say that applicable variants are expected to work.
* List RISC-V (known to work, being tested).
* List SuperH and M88K (code exists, unknown status, like M68K).
* De-list VAX and remove code (known not to work).
* Remove stray trace of Alpha (support was removed years ago).
* List illumos, DragonFlyBSD (known to work, being tested).
* No need to single Windows out by listing a specific version, when we
don't do that for other OSes; it's enough to say that we support
current versions of the listed OSes (when 16 ships, that'll be
Windows 10+).
