littledan 8adb1c4705 Reland of Check that array length stays a safe integer in Array.prototype.push (patchset #1 id:1 of https://codereview.chromium.org/1418093007/ ) 
Reason for revert:
The test failure was unrelated; relanding.

Original issue's description:
> Revert of Check that array length stays a safe integer in Array.prototype.push (patchset #7 id:120001 of https://codereview.chromium.org/1428483002/ )

> Reason for revert:
> Caused for-in-opt test to fail

> Original issue's description:
> > Check that array length stays a safe integer in Array.prototype.push
> >
> > This patch adds a check in Array.prototype.push to assert that the new
> > length does not become greater than 2**53-1. Such a length would be
> > dangerous because integer arithmetic becomes imprecise after the
> > boundary. The check is also required by a test262 test.
