Canonicalize bitcasts between types like <1 x i64> and i64 to
insertelement/extractelement.

I'm not entirely sure this is precisely what we want to do: should we
prefer bitcast(insertelement) or insertelement(bitcast)?  Similarly. should we
prefer extractelement(bitcast) or bitcast(extractelement)?
