Michael Sproul 84e6d71950 Tree hash caching and optimisations for Altair (#2459) 
## Proposed Changes

Remove the remaining Altair `FIXME`s from consensus land.

1. Implement tree hash caching for the participation lists. This required some light type manipulation, including removing the `TreeHash` bound from `CachedTreeHash` which was purely descriptive.
2. Plumb the proposer index through Altair attestation processing, to avoid calculating it for _every_ attestation (potentially 128ms on large networks). This duplicates some work from #2431, but with the aim of getting it in sooner, particularly for the Altair devnets.
3. Removes two FIXMEs related to `superstruct` and cloning, which are unlikely to be particularly detrimental and will be tracked here instead: https://github.com/sigp/superstruct/issues/5

Ethereum 2.0 Specification Tests

This crate parses and executes the test vectors at ethereum/eth2.0-spec-tests.

Functionality is achieved only via the $ cargo test --features ef_tests command.

Running the Tests

Because the test vectors are very large, we do not download or run them by default. To download them, run (in this directory):

$ make

Note: this may download hundreds of MB of compressed archives from the ethereum/eth2.0-spec-tests, which may expand into several GB of files.

If successful, you should now have the extracted tests in ./eth2.0-spec-tests.

Run them with:

$ cargo test --features ef_tests

The tests won't run without the ef_tests feature enabled (this is to ensure that a top-level cargo test --all won't fail on missing files).

Saving Space

When you download the tests, the downloaded archives will be kept in addition to the extracted files. You have several options for saving space:

  1. Delete the archives (make clean-archives), and keep the extracted files. Suitable for everyday use, just don't re-run make or it will redownload the archives.
  2. Delete the extracted files (make clean-test-files), and keep the archives. Suitable for CI, or temporarily saving space. If you re-run make it will extract the archives rather than redownloading them.
  3. Delete everything (make clean). Good for updating to a new version, or if you no longer wish to run the EF tests.
