This fixes an issue where service RPCs are not answered by the
vm-service.
Currently new isolates are visible via the service protocol immediately
after creation. This means a vm-service client can start doing service
RPCs to a particular isolate. If the embedder has not-yet installed a message
handler the OOB messages will be queued up.
Once the embedder installs an isolate message notify handler, that
handler needs to be invoked if there are pending messages.

This makes the ImageWriter remember at which offsets it wrote
RawInstructions.
This is preparation work for allowing the ImageWriter write the
instructions in a specific order (currently instructions are written
"on-demand" when the object serializer encounters references to them)

Threads in the native or blocked states don't prevent safepoints, so they may run concurrently with a safepoint operation like GC. It is not safe for handles to be allocated while the GC is visiting them, so these threads must not allocate handles. Assert only threads in the VM or generated states, which prevent safepoints until they check in, may allocate handles. (Generated code does not allocate handles, but leaf runtime entries remain in the generated state.)

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.
