This introduces three new types OtherCallable, CallableProxy (and OtherProxy),
and BoundFunction to make it possible to express Callable in the Type system.
It also forces all undetectable receivers to be Callable, which matches the
use case for undetectable, namely document.all (guarded by proper checks and
tests).
It also uses these new types to properly optimize instanceof (indirectly via
OrdinaryHasInstance) based on the type of the constructor and the object. So
we are able to constant-fold certain instanceof expressions based on types
and completely avoid the builtin call.
