 * Brendan: "need to test cases Math.pow(2,32) and greater to see
 * whether they round-trip." Reason: thanks to the work done in
 * http://bugzilla.mozilla.org/show_bug.cgi?id=124339, lastIndex
 * is now stored as a double instead of a uint32 (unsigned integer).
 *
 * Note 2^32 -1 is the upper bound for uint32's, but doubles can go
 * all the way up to Number.MAX_VALUE. So that's why we need cases
 * between those two numbers.
