[webkit-dev] Test coverage for FrameLoader

[Adam Barth]

The usual WebKit policy is not to accept functional changes without
regression tests.  I'd like to ask that this policy be enforced
strictly for FrameLoader.  For example, I don't think we should be
taking changes like this without tests:

https://bugs.webkit.org/show_bug.cgi?id=30573

This policy is going to block fixing some FrameLoader bugs until we
creating a better loading test harness, but I think the long-term
benefits will out-weigh the short term costs.
