X87: [es6] Initial steps towards a correct implementation of IsCallable.

X87: [es6] Initial steps towards a correct implementation of IsCallable.

port 8a378f46d52ce64578c71313ed76a67592fbf63c (r30552)

original commit message:

    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.
