Bug 1635094 - Cleanup the ReferrerInfo code. r=ckerschb

Browse Source 
The cast in InitWithNode is wrong. AsElement() asserts instead of
checking the flag, so we always pass an element (and if we didn't we'd
have type confusion problems). I audited the callers and we're fine.

Anyhow, always require an element, and add two convenience constructors
for C++ code.
