Bug description:Regression in 8.1: sorting dates differ from > operator

Description:
------------
Previously (PHP 7.4 and 8.0) when a date with year = PHP_INT_MAX were >
to a date with any lower year, it was convenient to represent an
absolute maximum. And it was rather expected.

Now in 8.1 (latest on GitHub Actions), it became lower.

Test script:
---------------
var_dump(
    (new DateTimeImmutable('2000-12-31
23:59:59.999999'))->setDate(PHP_INT_MAX, 12, 31) >
    new DateTimeImmutable('2019-01-26 10:30:12.000000')
);

Expected result:
----------------
true

Actual result:
--------------
false
