Summary:
Now that we have a way to write cost issues, let's not rely on some arbitrary threshold (and also get rid of `EXPENSIVE_EXECUTION_TIME` issues in tests).
One consequence of this is that we will loose the cost traces in tests since `costs-report.json` doesn't have any traces. Next diff fixes that.

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. The <fname> found in 1 should be followed by a space, '<', '(', or end of line.

Summary: Add a flag `is-inclusive-cost` (`true` by default) which computes inclusive cost for each function. Setting the flag to `false` computes exclusive cost of the function where the cost of the callees are assumed to be `0`.
