[Code]: There are redundant loop variables in Compare.move

[0xOutOfGas]

Framework version: v11
Description: In function Compare::cmp_bytes(), the loop variables i1and i2 are redundant.
Code Location: sources/Compare.move, line 57

public fun cmp_bytes(v1: &vector<u8>, v2: &vector<u8>): u8 {
    let l1 = Vector::length(v1);
    let l2 = Vector::length(v2);
    let len_cmp = cmp_u64(l1, l2);
    let i1 = 0;
    let i2 = 0;
    while (i1 < l1 && i2 < l2) {
        let elem_cmp = cmp_u8(*Vector::borrow(v1, i1), *Vector::borrow(v2, i2));
        if (elem_cmp != 0) {
            return elem_cmp
        };
        // else, compare next element
        i1 = i1 + 1;
        i2 = i2 + 1;
    };
    // all compared elements equal; use length comparison to break the tie
    len_cmp
}

Recommendation: Remove i2, and change *Vector::borrow(v2, i2) to *Vector::borrow(v2, i1). Also the comparison (elem_cmp != 0) can be changed to (elem_cmp != EQUAL) for clarity.
