12e62e7154 Shorten constructor names in JS tickprocessor.
As they are no more used in DevTools profiler, there is no
need to prefix them with "devtools.profiler" namespace.

e0b829b1a5 TickProcessor: more accurate mapping of statically compiled code on Linux.
'nm' is now called with an option to report function code sizes. Static code entries are restricted to the sizes reported, and the remaining unnamed code is attributed to a library as a whole. This makes reports more accurate, as some functions are tiny, but has chunks of unnamed code behind them.

This change doesn't affect reporting on Windows, as in .map files function code sizes aren't specified.

aa2c33126c 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.

It will be used both in the new tickprocessor and Dev Tools profiler.
