Early evidence is this breaks Bazel's own tests: `//src/test/shell/bazel:bazel_bootstrap_distfile_test` fails because of a `grpc` repo dependency with `cfg="host"`.

The current name is `--fail_on_analysis_cache_discard`. @mattem noted an alternative suggestion is `--disallow_analysis_cache_discards`....

I'm fine with `allow_analysis_cache_discard` (the core flag is defined with as a positive action, without negations). And the boolean parsing logic automatically supports the `no` variant. I'm generally fine with...

Hey @mattem - I saw you had some new commits recently. Were you ready for the next (last?) round?

Everything looks good to me, aside from the branch conflict (I imagine it's not a big one) and the failing CI. [One](https://storage.googleapis.com/bazel-untrusted-buildkite-artifacts/0187c425-d8e0-4a89-8efb-0fbd4143b47b/src/test/java/com/google/devtools/build/lib/analysis/AnalysisTests/shard_5_of_12/test_attempts/attempt_1.log) of the CI failures is: ``` Executing tests...
