      Fix 'illegal access' in Date constructor edge case · a9c79100
      littledan authored 
      In a rare edge case, a difference in checks between C++ and
JavaScript lead to an 'illegal access' being thrown by the Date
constructor. This patch harmonizes the checks from both sides.
It's possible that slightly larger dates could be permitted,
as the ECMAScript 2015 specification indicates that +287396-10-12
would be a permissible date in the note in
http://tc39.github.io/ecma262/#sec-extended-years
This patch does not revisit the limit, only clears up the
inconsistency.

Reason for revert:
Should be fixed again with this Blink change to add NeedsManualRebaseline
