Allow navigations to frames that aren't being unloaded in the unload handler.

Allow navigations to frames that aren't being unloaded in the unload handler.

This change lets the page navigate frames that aren't being unloaded in
the unload handler. For example, a popup may want to navigate its
opener while it's being closed.

FrameLoader now also correctly checks if the |targetFrame| can be
navigated, instead of checking if |m_frame| can be navigated.
