[cost] Re-locate where to print issue with heuristics Summary: Currenlty the cost issue is printed at the first node of a function, which is usually the first statment of the function. This may give a wrong impression that the cost of the statement is changed. This diff re-locate where to print issues with heuristics. Going backward from the first node lines, it looks up a line satisfying, 1. A line should start with <fname> or should include " <fname>". 2.
