The single underscore version is actually slightly more supported among
the compilers I've seen so far. Also added the exact list now.

eeb4e7e changed the final C translation unit that used this header to
C++, and we got some more helpful inline functions upcoming.

DOS is not the same thing as the underlying CPU, after all. A separate
file not only indicates to future port authors which parts of the code
are x86-specific, but it also speeds up build times…
… in theory, because removing 677 lines from 49 files each doesn't seem
to speed up the build as much as I had hoped? But apparently my whole
system mysteriously got faster in the meantime, and I was getting 22-23
seconds for the entire repo even before this commit. Good enough.

This might have almost been the case that justified making master.hpp
compatible with C translation units… but even this one would like to
use the template functions from th01/math/vector.hpp.
