Some of these are already in defaults.h. (Of course all defaults should
be documented in tm.texi as well.)

Defaults to (BITS_PER_UNIT * MIN ((UNITS_PER_WORD + 1) / 2, 2)).
I expect most definitions could go away.

Defaults to BITS_PER_UNIT, all values are equal to that, and I don't know
whether support for it being different really works in practice.

Defaults to BITS_PER_WORD.
While dealing with this sort of cruft, WCHAR_UNSIGNED doesn't seem to be
used anywhere. Is it meant to be useful? If not, it should probably die
too.
