This adds backends comparison in data extractor. It performs
comparison on a fixed list (CPU, GPU, HPU) for 64 bits precision
ciphertext as displayed in tfhe-rs public documentation.
SVG table generation is automated via the documentation benchmark
workflow.
This is done to avoid confusion for operations that might have the same between layer. For example, 'bitand' operation have the same name for shortint and integer layers
When doing regression generation, one can provide a global parameters set name pattern to filter head branch benchmark results.
This fixes the issue encountered when there are more than one parameters' set used to benchmark an operation, for example, in core_crypto or shortint tfhe-rs layer.
After running performances regression benchmarks, a performance
changes checking is executed. It will fetch results data with an
external tool then it will look for anomaly in changes.
Finally it will produce a report as an issue comment with any
anomaly display in a Markdown array. A folded section of the
report message contains all the results from the benchmark.
Note that a fully custom benchmark triggered from an issue comment
would not generate a report. In addition HPU performance
regression benchmark is not supported yet.
