description:
track direct caller in stack frames

* stack-frame.h, stack-frame.cc (stack_frame::m_parent_link): New data
member to track direct parent, not just user-defined function, script,
or scope frames as m_static_link does.
(stack_frame::parent_link): New function.
(stack_frame::stack_frame): Accept parent_link argument.  Change all uses.
(stack_frame::create): Accept parent_link argument.  Change all uses.

* call-stack.cc (call_stack::pop): Set m_curr_frame to parent_link,
not static_link.


This is a blocker for the 6.1 release.
