The memory savings from this flag are not worth the complexity, and it interferes with action restarting.
RELNOTES: Remove support for --discard_actions_after_execution.

come from Skylark, so we shouldn't crash. As a safety measure, subclasses of ActionLookupValue are now responsible for detecting action conflicts themselves.

removing the layer of indirection of getting SkyKey out of ActionLookupKey, which uses more memory for no reason.

This key context can be used by actions to share partial key computations, for instance when computing MD5s for nested sets.

Blaze had its own class to avoid GC from varargs array creation for the precondition happy path. Guava now (mostly) implements these, making it unnecessary to maintain our own.
This change was almost entirely automated by search-and-replace. A few BUILD files needed fixing up since I removed an export of preconditions from lib:util, which was all done by add_deps. There was one incorrect usage of Preconditions that was caught by error prone (which checks Guava's version of Preconditions) that I had to change manually.

precomputed value. Instead, manually check if the value has changed, and if it has, invalidate its consuming WorkspaceStatusValue node, forcing its re-evaluation, where it will pick up the new value.
This seems more awkward than the original code, but it is more correct in spirit: injecting a precomputed value which can change even while the source state does not is a smell. Long-term, the key for the WorkspaceStatusValue should incorporate a hash of the action, and that hash should be in the configuration, just as other configuration flags are. That isn't possible right now just because we don't have configuration trimming, and we drop all nodes on configuration changes, so putting workspace status options into the configuration would lose change pruning whenever we changed workspace status options.
If/when those problems are fixed, we can extend this change to have WorkspaceStatusFunction continue to request the action out-of-band, but keyed by the hash. Then we can stop invalidating stale nodes.

--noexperimental_enable_critical_path_profiling flags are all specified, then Bazel will delete Actions from ActionLookupValues as they are executed in order to save memory.
Because an already-run action may output an artifact that is only requested later in the build, we need to maintain a way for the artifact to look up the action. But in most cases we don't need to keep the action itself, just its output metadata.
Some actions unfortunately are needed post-execution, and so we special-case them.
Also includes dependency change with description:
Move action out of key. This keeps action references from polluting the graph -- actions are just stored in one SkyValue, instead of being present in SkyKeys.
This does mean additional memory used: we have a separate ActionLookupData object per Action executed. That may reach ~24M for million-action builds.

The only place we now don't handle InterruptedException is in the action graph created after analysis, since I'm not sure that will be around for that much longer.

The headers were modified with
`find . -type f -exec 'sed' '-Ei' 's|Copyright 201([45]) Google|Copyright 201\1 The Bazel Authors|' '{}' ';'`
And manual edit for not Google owned copyright. Because of the nature of ijar, I did not modified the header of file owned by Alan Donovan.
The list of authors were extracted from the git log. It is missing older Google contributors that can be added on-demand.
