For the few remaining uses of the builtin `i32` type, manually build an `IntType(Signed, 32)` value instead. These are: - The return type of `Run`. - The type that int literals in an `if` expression are converted into. - The type of an array index expression. We should consider converting those three cases away from `i32` over time. --------- Co-authored-by: Jon Ross-Perkins <jperkins@google.com>
