Weaken assertion in gen_snapshot requiring all libraries to have a loading unit as there can still be unreachable libraries: - Google3 and Fuchsia will compile all the sources in a package to a single dill file, then present multiple input dill files to the AOT compilation. Since the set of libraries was derived from package membership instead of imports, many can be unreachable. - When the root library's main comes from an export, the frontend's representation will incorrectly report the library containing main as the root library and the true root library may be unreachable from it. Instead, assert only that surviving compiled code is assigned a loading unit.
