Use only the incumbent global in postMessage#1573

Conversation
Previously one of the origin checks was performed with the entry settings object, while the origin and source attributes of the resulting MessageEvent were derived from the incumbent settings object. At least WebKit and Blink appear to use the same global for both, and it makes sense to align the checks on the same global. The difference is only observable in test cases that fiddle with document.domain, as entry and incumbent are always same origin-domain (but, in document.domain cases, not always same origin). Fixes #1542. Helps #1431 but hurts #1430.

This looks good. I filed #1579 for other problems I noticed while reviewing. |

I don't think this needs needs review from Boris or Bobby since any editor should be able to verify this just implements what was discussed in #1542, so I'll avoid pinging them.
