Previously, the Intl.DateTimeFormat constructor and other related paths had
a bug where the options bag passed in would be modified in place. This patch
makes V8's Intl implementation follow the specification's logic to avoid
such a modification.

It's in stage 4 and Firefox has already implemented it.

For now, it's added to HARMONY_IN_PROGRESS bucket behind

This patch removes the following properties, as their use count is
very low, they are V8-only, and not on a standards track.
- v8Parse
- resolved
- pattern

v8BreakIterator is left in as it has significantly more usage.

A couple of the Intl tests made calls to getDefaultTimeZone(), which
doesn't exist in V8; however, these were not core to the test. Rather
than marking the whole test as failing, just comment out that
unimportant part of the test.

ECMAScript dates act as if the Gregorian changeover happened at the
beginning of time. This patch fixes up internationalized date
formatting to set that changeover properly, as opposed to the ICU
default which is in the 16th century.

Reverting reverted r17148 and fixing build (test) breakage by side stepping the Windows vs. Linux issue of different Date object for the same millisecond time stamp.
We do that by using UTC Date methods (they eliminate DST problems).

Windows:
new Date(129193200000);
Sun Feb 03 1974 23:00:00 GMT-0800 (Pacific Standard Time)

Linux:
new Date(129193200000);
