Patch in progress

Here's a patch in progress. It fixes the bug, but the code is somewhat ugly. I
made it by inlining the calls to getCallFrame() and getCallerFunctionOffset()
and modifying the logic to handle this special case. I am not quite sure of the
necessity of the second if (!exec) at this hour.

When the caller functionality was added to SquirrelFish, a test case was added
to fast/js/function-dot-arguments-and-caller.html that codifies the behaviour
in the bug. This is the only JavaScriptCore or layout test that this patch
fails, and JavaScriptCore also fails this test prior to SquirrelFish.
