43bf8f9754 Add source map support to tick processor.
Added a console parameter for source map to the tick processor.
The tickprocesspor reads in the source maps and uses it to output the original filename, line number and column in the profile.
Modified d8 to output column numbers into the log, since this is needed to do source mapping.

37d3972429 Fix issue 571: display descriptive names for code objects from snapshot.
As this is only needed for internal profiling (not for DevTools),
the following approach had been chosen:

 - during snapshot creation, positions of serialized objects inside
   a snapshot are logged;

 - then during V8 initialization, positions of deserealized objects
   are logged;

 - those positions are used for retrieving code objects names from
   snapshot creation log, which needs to be supplied to tick processor
   script.

Positions logging is controlled with the new flag: --log_snapshot_positions.
This flag is turned off by default, and this adds no startup penalty.

To plug this fix to Golem, the following actions are needed:

 - logs created using 'mksnapshot' need to be stored along with VM images;

 - tick processor script needs to be run with '--snapshot-log=...' cmdline
   argument.

BUG=571

32b0e47fa5 Add automatic tests for Tick Processor, take two.
Now tests can be run from any directory. Location of test data is now determined using test file location provided by 'testcfg.py' script.

Tested under Linux, Mac, and Windows.
