Pass frame construct events to unwind info writer for JSFunction calls

Unwinding info keeps track of the frame pointer by tracking the changes
to the stack if a frame wasn't constructed. Once the frame is constructed
we no longer need to keep track of this. The code generator informs
the unwinding info writer about frame constructions. This information
was not passed for JSFunctions calls. This cl fixes it to pass also
for JSFunctions.
