This CL normalizes all status files by the status file normalizer found at
pkg/status_file/bin/normalize.dart.
To make sure all status files are kept in pristine condition, a linter is placed
on the presubmit hook. The linter can be found at pkg/status_file/bin/lint.dart.

Coverage uses the value of an execution counter to detect executed functions. However non-positive execution counter does not necessary mean that a function was never executed because we sometimes reset the counter.
Introduce additional bit on a function that is set whenever we reset positive execution counter and use this bit when generating coverage data.

Improves the space overhead of compaction from O(size of live objects) to O(number of live objects).
Future work includes:
- a smaller, faster representation the forwarding table via a bitmap of used allocation units
- sorting class sizes off-heap to allow sliding classes
- running forwarding in parallel
Removes unnecessary sweep from evacuating compactor.

The compactor copies all live objects in old space to fresh pages, places forwarding pointers in the old objects, forwards all the pointers, then frees the old pages. This has a high space overhead. It is not meant for use in production, but meant to test that the VM is properly set up to handle old-space objects moving.
Large page objects and instruction objects are not moved.

- Refactoring of the TimelinePage in order to remove the
dependencies from the Service objects.
- Implemented TimelineRepository to abstract the communication layer
- Structured new TimelineDashboardPage with simplified UI and event
filtering
The VM returns lists of events which are forwarded to Catapult.
Some events are white-listed for the common user.
Due to limitations in the way the events are generated the only way to
attach the white-list flag to the events is by adding an extra argument.
By setting the hash of timeline.html to #basic we inform JavaScript that
we require the activation of the filter which forwards just the events
white-listed to Captapult, while preserving all the others during
dumping operations.

Summary:
Previously, we would create a wrapper function in the flowgraph around converted
closures, which would forward all the closure's arguments and unpack the context
argument before calling the real closure function.
Now, we perform the unpacking at the top of the real function to avoid having
any wrapper function.
Previously, captured parameters would still be appear live to the GC even if
they're updated, because after they are copied into the context, all updates to
them are done there.
Now, as in regular closures, we zero-out the parameter variable after copying
it's value into the context, avoiding potential memory leaks.
Test Plan:
Ran the closure conversion test suite.
Ran benchmarks on Golem -- all statistically significant regressions are gone.

Review-Url: https://codereview.chromium.org/3008923002 .
Status:
- Currently the getIsolate API tries to guess the status of the isolate
when it is in between the IsolateRunnable and PauseStart, by reporting
it as already in the PauseStart status.
This can potentially make flaky all the tests that uses PauseStart to
synchronize with the actual status of the Isolate.
- In the previous situation the timestamp of the event is guessed too,
potentially reporting a wrong value.
- Even with the previous fix the is still a race condition that can lead
to a getIsolate responde with a PauseStart status to be sent before
the actual PauseStart event.
Changes:
- Fallback to None pause event if the isolate is in between
IsolateRunnable and PauseStart, avoiding double posting.
- Send the PauseStart event before the actual status change, partially
avoiding the race conditions.
- Set the pause timestamp before the actual status change, fully
avoiding the race condition.
