Revert 108752 - Support tracking of IPC messages as tasks in profiler
Also started to do more cleanup, including creating a base/profiler directory, and moving parts of the over-sized tracked_objects.* into that directory. r=rtenneti Review URL: http://codereview.chromium.org/8480014 TBR=jar@chromium.org Review URL: http://codereview.chromium.org/8496008 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@109004 0039d316-1c4b-4281-b951-d872f2087c98
