Summary
DateConversion::formatDateTime incorrectly formats negative years

Test case: d = new Date; d.setFullYear(-12); d.toUTCString().split(" ")[3] Expected: "-0012" Math.abs(year) should be padded to length of 4 and preceded with "-" if year < 0. Actual: "-012" JSC always pads year to length of 4, including minus sign "-". Other browsers engines comply with the spec. ECMA262:
https://tc39.es/ecma262/#sec-datestring
(steps 6-10) Test262:
