[code-reflection] RFR: Use buffer tagger for minimizing copies

[Ruby Chen]

Use the result of the buffer tagger for labeling buffer accesses. The manual annotations and the results of the buffer tagger are still compared with an assertion.

Also fix manual annotations and prevent buffer tracking from being injected for an accelerator.
