Richard SmithandDana Jansens bba32900c3 Preserve type sugar in ArrayType, ConstType, and PointerType. (#5235) 
Each of these types takes another type as an operand. Instead of storing
that other type as a `TypeId`, store it as an `InstId` so that we can
track how it was written, not only its canonical form.

The canonical constant values of these types continue to store the
canonical constant values of their operands, as normal.
