Array.prototype.fill negative arg semantics

[rwaldron]

Actual:

console.log( [1, 2, 3].fill(4, -3, -2) );    // [1, 2, 3]

Expect:

console.log( [1, 2, 3].fill(4, -3, -2) );    // [4, 2, 3]
// length = 3
// 3 + -3 = 0 <-- calculated start
// 3 + -2 = 1 <-- calculated end

From spec:

If start is negative, it is treated as length+start where length is the length of the array. If end is negative, it is treated as length+end.
