  [LVI] Fix insertelement of constexpr

Bail out when evaluating an insertelement of a constant expression.
Unlike other ValueLattice kinds, these don't have implicit splat
semantics and we end up with type mismatches. If we actually wanted
to handle these, we should actually evaluate the insertion via
constant folding. I'm not bothering with that, as these should
get constant folded on construction already.
