Update topCallFrame when calling host functions in the JIT
https://bugs.webkit.org/show_bug.cgi?id=67010
Patch by Juan C. Montemayor <[email protected]> on 2011-08-26
Reviewed by Oliver Hunt.
The topCallFrame is not being updated when a host function is
called by the JIT. This causes problems when trying to create a
stack trace (https://bugs.webkit.org/show_bug.cgi?id=66994).
