Nathan Froyd 846d8789ee Bug 1492894 - part 1 - make the node hierarchy consistently constructed with NodeInfo&&; r=mccr8
Various places in dom/ use the pattern:

  already_AddRefed<NodeInfo> ni = ...;

which is supposed to be disallowed by our static analysis code, but
isn't, for whatever reason.  To fix our static analysis code, we need to
eliminate instances of the above pattern.

Unfortunately, eliminating this pattern requires restructuring how Nodes
are created.  Most Node subclasses take `already_AddRefed<NodeInfo>&` in
their constructors, and a few accept `already_AddRefed<NodeInfo>&&`.  We
need to enforce the latter pattern consistently, which requires changing
dozens of source files.
