[Bug 22858] use @@hasInstance instead of [[HasInstance]]

https://www.w3.org/Bugs/Public/show_bug.cgi?id=22858

--- Comment #4 from Anne <annevk@annevk.nl> ---
That did not happen for e.g. ArrayBuffer. Another example would be promises,
which in Gecko are implemented in terms of IDL and therefore have this
"feature".

bz, did we consider something like

  Window.ignoreGlobalInstanceOf(..., ...)

as that seems hardly different from what this magic @@hasInstance override is?
