Add const modifier to initialPreLocal identity matrix.

This makes expressions with `initialPreLocal` eligible for constant
folding. In practice, this doesn't do much today because matrix constant
folding doesn't support no-op-arithmetic elimination, but in a followup,
we could easily simplify `initialPreLocal * foo` --> `foo` when it's the
identity matrix.
