The ZoKrates front-end now represents ZoK arrays as IR arrays, and ZoK structures as (type-tagged) IR tuples.
During this change, I discovered that IR support for eliminating tuples and arrays was not complete.
Thus the change list is:
The ZoK front-end uses IR arrays and tuples
Improve IR passes for array and tuple elimination
Enforce cargo fmt in CI
Bugfix: handle ZoK accessors in L-values in the correct order
Bugfix: add array evaluation to the IR
This PR does not:
implement an array flattening pass
implement permutation-based memory-checking
Benefits:
The ZoK->R1CS compiler is now ~5.88x faster (as defined by the time it takes to run the tests in master's scripts/zokrates_test.zsh script: this goes from 8.59s to 1.46s)
For benchmarks with multi-dimensional arrays, the ZoK->R1CS compiler can now compile them with reasonable speed. Before it it would time out on even tiny examples.
The ZoK->R1CS compiler will be able to benefit from future memory-checking improvements
IR support for arrays and tuples is complete now, making those parts of the IR more accessible to future front-ends.
