Reproduction steps:

2. execute following code
WeakSet();
Actual result:
following error message is shown

Expected result
It shows more helpful message, like "Map()" shows following

The WeakSet constructor was already fixed in bug 1215814 (https://hg.mozilla.org/integration/mozilla-inbound/rev/76b54ac73786).
