LGTM (kind of rubberstamp).

https://codereview.chromium.org/15640002/diff/1/runtime/vm/raw_object_snapsho...
File runtime/vm/raw_object_snapshot.cc (right):

https://codereview.chromium.org/15640002/diff/1/runtime/vm/raw_object_snapsho...
runtime/vm/raw_object_snapshot.cc:576: ASSERT(kind != Snapshot::kMessage);
This assertion looks redundant now.

https://codereview.chromium.org/15640002/diff/1/runtime/vm/raw_object_snapsho...
runtime/vm/raw_object_snapshot.cc:605: ASSERT(kind != Snapshot::kMessage);
Ditto.

https://codereview.chromium.org/15640002/diff/1/runtime/vm/raw_object_snapsho...
runtime/vm/raw_object_snapshot.cc:627: ASSERT(kind != Snapshot::kMessage);
Ditto.

https://codereview.chromium.org/15640002/diff/1/runtime/vm/raw_object_snapsho...
runtime/vm/raw_object_snapshot.cc:656: ASSERT(kind != Snapshot::kMessage);
Ditto (and throughout the file).

Good point. Removed that assertion.
