* Roll Dart SDK to ed00447138f95ea4ba612509a244ca8205735372 Make the VM happy with a spurious instruction snapshot. * Revert "Snapshots: Don't use an empty array where a NULL array is expected. (#3361)" This reverts commit 275ffdcef80ffb85f4be62b9e8d1b17b5c0fdacf. Broke iOS simulator builds; should no longer be necessary after rolling the Dart SDK to ed00447138f95ea4ba612509a244ca8205735372. On iOS simulator builds, we were seeing DartLookupSymbolInLibrary return a pointer to a address of the snapshot data rather than the address of the snapshot buffer itself. On simulator builds we don't build the snapshot data into a buffer in app.dylib (kDartVmSnapshotData) but link it statically into the engine itself.
