Test262 is showing wrong ordering of option property accesses compared to the latest PR.

This patch implements fractionalSecondDigits option for Intl.DateTimeFormat. If it is
specified, milliseconds in N digits are represented in the formatted output.
This extension is about to be merged into the spec[1]. SpiderMonkey and V8 support it,
and V8 shipped it without flags.
