The above hunk looks wrong and regresses

The prefetch intrinsics can't be pure, after all they return void, so
as pure are always optimized away.

Ok for trunk if it passes bootstrap/regtest?

Looks obvious to me, especially after the above explanation.

Thanks,

Ok.

Whoops - sorry for not noticing.  Looks like "pf" means prefetch here,
so technically they are pure (do not write to memory) but we don't want to 
DCE them as they have additional side-effects.  We could mark them
looping-const-or-pure I guess, or "volatile" (which we can't express for
calls IIRC).
