    Ensure Array.prototype.indexOf returns +0 rather than -0 · 8798ef2d
    littledan authored
    A recent ES2016 draft spec clarification indicates that, if -0 is
    passed into Array.prototype.indexOf or Array.prototype.lastIndexOf
    as the starting index, and the result is found at index 0, then +0
    rather than -0 should be returned. This patch ensures that V8 has
    that result, which is consistent with what some other browsers
    return. The patch allows a couple test262 tests to pass.
