Keep track of topCallFrame for Stack traces
https://bugs.webkit.org/show_bug.cgi?id=66571

Patch by Juan C. Montemayor <jmont@apple.com> on 2011-08-24
Reviewed by Geoffrey Garen.

This patch adds a TopCallFrame to JSC in order to have that information
when an error is thrown to create a stack trace. The TopCallFrame is
updated throughout select points in the Interpreter and the JSC.
