[lld-macho] -weak_{library,framework} should always take priority We were not setting forceWeakImport for file paths given by `-weak_library` if we had already loaded the file. This diff fixes that by having `loadDylib` return a cached DylibFile instance even if we have already loaded that file. We still avoid emitting multiple LC_LOAD_DYLIBs, but we achieve this by making inputFiles a SetVector instead of relying on the `loadedDylibs` cache.
