Currently Execution::Call (and friends) still duplicate a lot of the
Call sequence logic that should be encapsulated in the Call and
CallFunction builtins. So the plan now is to switch Execution::Call
to accept any Callable and just pass that through to the Call builtin.

We already disallowed observing the global proxy; now we also
disallow any observation of access-checked objects (regardless
of whether the access check would succeed or fail, since there's
not a good way to tell the embedder what kind of access is being
requested).
Also disallow Object.getNotifier for the same reasons.

This makes sure that the arguments object materialization in the method
prologue is composable with respect to inlining. The generic runtime
functions materializing those objects now respect the deoptimization

which pushes a sequence of arguments onto the stack and calls
builtin::Call.

Inner functions must be eagerly parsed for scope analysis, but the full AST is
also kept around even though it's not needed.
This CL mitigates this problem by allocating some AstNodes of the inner function
to a temporary Zone which is deallocated once the scope information has been
built. The remaining nodes (such as VariableProxy) must persist until scope
analysis actually happens, and have to be allocated to a parser-persistent Zone.

Similar to DELETE, the IN builtin is just a thin wrapper for %HasElement

special fast case (which also involved at least one LOAD_IC plus some
intrinsic magic).

This turns the has_instance_call_handler bit on Map into an is_callable
bit, that matches the spec definition of IsCallable (i.e. instances have
[[Call]] internal methods).
Also fix the typeof operator to properly say "function" for everything
that is callable.
Also remove the (unused) premature %_GetPrototype optimization from
Crankshaft, which just complicated the Map bit swap.
