In rare cases a summary package bundle may contain a LinkedLibrary object but not its corresponding UnlinkedUnits. (This could happen, for instance, if both a package and one of its dependencies contain libraries that reference the same file as a "part"--in this case, the UnlinkedUnit for the part might only be included in one of the package bundles, because it is redundant in the other). This CL modifies dump_inferred_types.dart so that it doesn't crash in this rare corner case. R=scheglov@google.com Review URL: https://codereview.chromium.org/1930663003 .
