Reviewed by Simon Fraser.

Tests that rely on multiple 'iframe' elements loading in a specific
order are a Bad Idea™. This patch splits
'fast/frames/sandboxed-iframe-scripting.html' out into five tests, and
changes two of them (#2 and #4) to use message passing in order to
test in a way that 'js-test-{pre,post}' can cleanly report.
