Derived from bug 1394682.

Currently the template object is stored per each compartment, and sweeped for each GC.
the template object uses Unknown type for "value" property, since the template object is shared between generators.

we could create the template object for each async generator, and add better type information (from the initial value maybe?).
I haven't checked if this really introduces performance gain tho.
