This change collects additional information related to ReceivePort
allocation locations and an optional debug name that will be displayed
by tooling. ReceivePort is now a special InstanceKind and a ReceivePort

Don't flatten snapshot chunks into a linear byte array to avoid a 2GB limit in JS. The lifts the largest snapshot we can handle to either 2^32 objects or the memory limit in JS.

This improves the time to deserialize a snapshot. It also doubles the memory needed to receive the snapshot buffer, but the memory high water mark is still computing the dominators.

This replaces _requestHeapSnapshot and _getObjectByAddresses, which relied on the invalid assumption that objects don't move and the heap hasn't mutated since the initial snapshot.
Updates Observatory to the new format. Adds treemap visualization of the dominator tree. Adds the ability to save and load heap snapshots to files. Removes analysis grouping references by source and target class. Removes ability to navigate from a pixel in the fragmentation view to inspector. Removes ability to query the top retaining instance from an ordinary class browser.

- Setting the `disableBreakpoints` parameter to true will result in any
breakpoints hit during execution resulting from an evaluate or invoke
call to be ignored.
- Default behavior is the same (break on breakpoints).
- Updated Observatory eval box to disable breakpoints.
- Added tests

In Dart2, type bounds checking is either performed by the common front-end or
by explicitly generated code, but not by type finalization or runtime anymore,
as it was done in Dart1.
Consequently, the class BoundedType is not needed anymore, and malbounded or
malformed types are not seen by the runtime either.

This forwarders are used at dynamic call-sites and perform type checking
for all non-generic-covariant arguments. This allows to skip the same
type checks in the actual method body.
This yield on average 10% improvement in performance across the body of
benchmarks including dart2js compilation times.
