Hash :9c05f55a Message :Capture/Replay: Add replay state validation.
We can use this to validate traces that have slight differences
when retracing. The valdation works by embedding the "expected"
JSON into a string at the end of each captured frame. The replay
also embeds a callback which fires right before the swap in the
replay harness. The harness then gets the "actual" JSON and runs
a comparison. On a mismatch it calls "diff" externally.
Currently the diff call is hard-coded to work on Linux only.
Note that when running validation it's important to replay on
SwiftShader since that's what we use to retrace.
