The benchmark action's "cargo" tooling assumes the standard bencher
output format, and can't parse criterion's output. Fortunately,
criterion can also provide bencher output for compatibility.
In order to pass criterion flags via `cargo bench`, we need to ensure
that all benchmarks use it (otherwise the flags are rejected by the
built-in benchmark harness as unknown). Since we don't actually have any
benchmarks inside the library itself, we simply disable its benchmark
harness.
- Added keygen benchmark.
- Refactored to extract common prover and verifier logic.
- Benchmarks are now grouped.
- Prover (and keygen) benchmarks now only take 10 samples instead of 100
(to make them feasible to collect in CI).
The workflow will comment on commits that cause a performance regression
of at least 200% (e.g. proving taking twice as long); we'll tune this as
we figure out how well benchmarking works on standard GitHub builders.
zcash/halo2#337 had been updated to account for `AssignedCell`, before
the change to simplify its bounds was made. `AssignedCell` now requires
the `From` impls to take `&VR`.
Clippy complained that it could be derived, but what we actually want is
for developers to be explicit about what rotations they are using, for
which `Rotation::cur()` is provided.
We only need V: Clone and for<'v> Assigned<F>: From<&'v V> for
specific methods.

Due to this error being detected and returned early, in practice
`minimum_k` would always be `current_k + 1`, and the error would be
returned repeatedly (as more of the circuit could be processed) until
`k` was set large enough. We now simply suggest that the user try a
larger value of `k`.
In most places within `CircuitLayout`, we are flexible on `k`. However,
for tracking selectors we need to know the number of rows. We could
change this, but given that we also want the number of rows to be
accurate for rendering unusable rows, we can instead use this as an
opportunity to inform the user that they will need to bump `k`.
