O.K., the breakage here is that athlon-xp is an SSE1 machine, and most of the
conversions in the patch require SSE2. It looks like SSE1 will support a few
of the new conversions (e.g. unsigned int32 <=> float); I'll see about enabling
these for SSE1 targets, and arranging for the SSE2-only conversions to fall
back to the x87.
