TickProcessor script reimplemented in JavaScript. This is an effort to reuse profiler data processing code both in TickProcessor and Dev Tools Profiler. The old Python implementation will be removed. The new TickProcessor works almost identical to the previous one. However, it has some differences: 1. Not very useful "Call profile" section is replaced with a new WebKit-like "Bottom up (heavy) profile" which shows the most expensive functions together with their callers. I used it personally in order to find and remove bottlenecks in the tickprocessor script itself, and found it quite helpful. 2. Code entries with duplicate names (they occur for RegExes, stubs and sometimes for anonymous Function objects) are now distinguished by adding an occurence number inside curly brackets. 3. (Address -> code entry) mapping is more precise in boundary cases. 4. Windows version no more requires specifying .map file location. 5. Works faster.
