Not completely sold on this, btw. But it's the path of least resistance (regarding code changes). |

During `bazel query`, `Label#getDisplayForm(mainRepoMapping)` might be called many many times. We can optimize for that case without sacrificing too much memory by computing a reverse mapping for the main repo mapping only. Fixes #20613. Closes #20617.

Thanks @Wyverald for a quick fix. FWIW I built bazel from your branch and confirmed this works on our repo. |
