I've had some time to look at this again. The problem's cropping
up in combine; combine_simplify_rtx ends up calling
gen_lowpart_for_combine (V2SFmode, const1_rtx), but
gen_lowpart_for_combine doesn't deal properly with the V2SFmode arguument.
Disabling the call to gen_lowpart_for_combine fixes the problem, but this
isn't a proper solution; I'm working on one now.

I've reproduced this crash in current cvs and I'll see if I can
fix the problem. I figured I should say something about it so others don't
duplicate the effort.
