Ryan Macnak 0cc70c4a7c [vm] Support for sharing parts of an app snapshot. 
In addition, this removes support for seeding the VM isolate snapshot with Instructions and referencing those Instructions in the isolate snapshot. This was leftover from an earlier experiment to share Instructions between a Core-JIT snapshot and App-JIT snapshots. Removing this reclaims the sign bit on Instruction offsets.

Add missing cases to TypeTestingStubFinder::StubNameFromAddresss.
