So I think we're ok with it, if only it makes the macros simpler.

I also think we should probably look at the m68k case, because while
that one seems to not have the bug that the arm case had, if we remove
the arm case the m68k code is now the only non-generic case remaining.

And it just makes me go "maybe we should get rid of the whole
'override the generic code' thing entirely?"

I don't think that inlining the first word (like the m68k code does)
is worth it, but it *is* possible that the architecture-specific
functions generate better code for some common cases, so I think this
is a "needs looking at the generated code" and not just a blind
removal.
