Change CallGraphNode to maintain it's Function as an AssertingVH

Browse Source 
for sanity.  This didn't turn up any bugs.

Change CallGraphNode to maintain its "callsite" information in the 
call edges list as a WeakVH instead of as an instruction*.  This fixes
a broad class of dangling pointer bugs, and makes CallGraph have a number
of useful invariants again.  This fixes the class of problem indicated
by PR4029 and PR3601.
