// Make sure that we properly scalarize tuples.
//
// TODO: This should be split out into its own pass /before/ DI rather than
// running during DI. Even once that happens, it is important that we update
// this test so that the test is in its post scalarization state so we can
// verify that DI can properly look through destructures.
