      Fix issue 553: function frame is skipped in profile when compare stub is called. · 999e3fca
      mikhail.naganov@gmail.com authored
      The problem appeared due to a fact that stubs doesn't create a stack
      frame, reusing the stack frame of the caller function. When building
      stack traces, the current function is retrieved from PC, and its
      callees are retrieved by traversing the stack backwards. Thus, for
      stubs, the stub itself was discovered via PC, and then stub's caller's
      caller was retrieved from stack.
      
      To fix this problem, a pointer to JSFunction object is now captured
      from the topmost stack frame, and is saved into stack trace log
      record. Then a simple heuristics is applied whether a referred
      function should be added to decoded stack, or not, to avoid reporting
      the same function twice (from PC and from the pointer.)
