    In RegExp, lastIndex is read with ToLength, not ToInteger · 1f61ac50
    littledan authored
    ES2015 made a change vs ES5, where the "lastIndex" property of a
    RegExp (which can be modified by a user to start the next search at
    a different location) is cast to an integer with ToLength rather
    than ToInteger. The main difference is on negative numbers, and
    this is tested by test262. This patch implements that change on
    RegExps and enables the test262 test now that it passes.
