Vectors of resources are logged incorrectly by the shape glue

[msullivan]

This program

resource mk(_x: int) { }

fn main() {
    let y = [mk(0), mk(1), mk(2), mk(3), mk(4)];
    log(error, y);
}

produces the following output:

rust: ~[res(0), res(, 1), res(, 2), res(, 3), res(, 4)]

[catamorphism]

No longer an issue; we don't have resources or shape glue, and the equivalent version with structs produces correct output.
