  "message": "Simplify InheritedLibraries\n\nThis CL simplifies the implementation of InheritedLibraries\nto use a UniqueVector\u003cconst Target*\u003e as well as a parallel\nvector of booleans (for the public flags). This doesn\u0027t\nchange the semantics of this type.\n\nCombined with the previous CL, measurements show that this\nsaves about 10% of \u0027gn gen\u0027 time, and 8% of peak RAM usage\nfor both Fuchsia and Chromium.\n\nBug: None\n\n--------------------------------------------------------\nFor Fuchsia\n\ngn-main\n\nDone.
