Fix crash with invalid out parameters. Many calls to `setRefKind` failed to check the return value; if it's false, an error has occurred and the program is in a bad state. Specifically, there is an assignment to a variable that's not marked as "written-to." If we continue processing the program, we're likely to assert.
