Extra-actions originating in Aspects are reported even if the rule we attach to also registers extra-actions. ExtraActionArtifactsProvider was using a set of ExtraArtifactSet, whose key was derived from the label of the owner of the extra-action. Since actions registered by Aspects have the same label as those registered by the base rule, the former ones would disappear from the set. An alternative to this CL would be to use an ArtifactOwner instead of a label as the key of the ExtraArtifactSet, but 1. BuildView only has access to ConfiguredTarget's, which lack the information to manipulate ArtifactOwner's; and 2. I don't see what ExtraArtifactSet gains us. In particular, ExtraArtifactSet.getLabel() is not used by anything outside of ExtraArtifactSet. The only disadvantage of this CL is that filtering (--experimental_extra_action_filter) can be slower if targets register a massive number of actions. Before this CL, we would match a single label per rule, while after this CL we match a single label per action. -- MOS_MIGRATED_REVID=139591862

Bazel is a build tool that builds code quickly and reliably. It is used to build the majority of Google‘s software, and thus it has been designed to handle build problems present in Google’s development environment, including:
A massive, shared code repository, in which all software is built from source. Bazel has been built for speed, using both caching and parallelism to achieve this. Bazel is critical to Google's ability to continue to scale its software development practices as the company grows.
An emphasis on automated testing and releases. Bazel has been built for correctness and reproducibility, meaning that a build performed on a continuous build machine or in a release pipeline will generate bitwise-identical outputs to those generated on a developer's machine.
Language and platform diversity. Bazel's architecture is general enough to support many different programming languages within Google, and can be used to build both client and server software targeting multiple architectures from the same underlying codebase.
