Run accuracy check at Diff time (#2388)
Summary:
X-link: https://github.com/pytorch/pytorch/pull/131266
Pull Request resolved: https://github.com/pytorch/benchmark/pull/2388
We can enable accuracy checks at Diff time since it is not a performance metric.
* Refactor the existing diff time test to use the new PT2 Benchmark Runner.
* Deprecate the speedup tests and enable the accuracy tests only. We rely on ServiceLab to perform performance testing and regression detection.
