Auto merge of #8226 - froydnj:gc-zeal, r=Ms2ger

unblock using JS_GC_ZEAL

I think these patches move the `JS_SetReservedSlot` call to the right place for #6057.  I'm not sure that the interface to `create_dom_global` is the best; passing a `JSVal` or a `*libc::c_void` seemed about equal, so I'd welcome feedback there.
