- Store actual field end positions instead of computing from a terminating semicolon.
- Consider unfinalized classes to be unchanged if they have same sequence of tokens.

This version of the Timeline allows the developer to see a logical
view over the operations involved in each frame.
Events are grouped by frame and shifted accordingly to avoid to have
overlapped frame.
See runtime/observatory/web/timeline.js for the undestrand the steps
involded in the process.

- 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.

An object A is said to be owned by object B if all direct references to A come from B. In particular, an object that holds unshared lists and maps will own the heap size of those lists and maps, as well as any unshared elements. We hope a table of owned sizes will be more useful than a table of shallow sizes, since the latter typically says the heap is mostly lists.

The Service Protocol exposes a new private RPC _getDefaultClassesAliases
which returns a Map from internal classes to a String.
This Map is used to group internal classes and to avoid navigation to
patch files.

The virtual-collection component uses a div container as a viewport on
a fixed sized spacer div that emulates the full size of the content.
In the spacer div there is a relative positioned div that scrolls
both horizontally and vertically. While the internal items are fully
computed horizontally, vertically we render just a subset of the items.
This buffer component scrolls both horizontally and vertically due
to its father child relationship with the spacer div. When the viewport
is going to show items that are not rendered in the buffer we move
the buffer accordingly (it is relative positioned with a variable top)
and update the content.
Managing the header of a table though is challenging:
1. we want the header to be fixed vertically
2. we want it to scroll horizontally accordingly to the the rest of the
content
3. we want also to make this container took into consideration during
the width computation, to allow it to trigger the horizontal
scrollbar if it is wider that content.
4. we want the header to perceive the same available space as the
other items in the collection.
We cannot obtain (1) at the same time of (2) (3) and (4) via pure
CSS. The header must be child of just another element.
- If we make it children of collection itself we obtain just (1) while
we need to emulate the others via code.
- If we make it children of the viewport we obtain (2) (3) and (4),
but we need to emulate (1) via code.
The first implementation followed the second option. The side effect
though is that smooth scroll (touch or touchpad based) does not fire
the onScroll events required to keep the header on top fast enough to
avoid flickering.
Due to the fact that scroll is the main use case for this element the
new implementation uses the first approach. Vertical flickering is
a problem no more. We obtain (2) by changing the horizontal offset
of the container, possible flickering, but way less common.
We obtain (3) by adding an extra div in the viewport which has the
same minimum size of the header. We obtain (4) by updating the
width of the last header child during the resize operations.

Moved the responsibility to provide MaxRSS and CurrentRSS from the VM to
the embedder.
The embedder can opt-it by setting a Dart_GetEmbedderInformation
callback using the public Dart_SetEmbedderInformationCallback API.
The implementation of the Dart_GetEmbedderInformation should mandatory
fill the version field and the ones it is able to fill.
The name field must reference a constant C style string, it will not be
freed by the VM code.

During the computation of the hover labels in the memory dashboard graph
the format functions were reading shared state that can be out of sync
if an update is ongoing.
To fix the error is enough to use the local copies instead.
To prevent this error in the future the format functions now are marked
as static and the analyzer will signal if they are accessing shared state.
