I think this is OK.

I'm less happy with doing this.  It makes it impossible to test the
pass-by-reference code paths without actually firing up a 32-bit
environment.  It'd be fine to document --disable-float8-byval as
a developer-only option (it might be so already), but I don't want
to lose it completely.  I fail to see any advantage in getting rid
of it, anyway, since we do still have to maintain both code paths.
