[turbofan] Constant-fold certain JSOrdinaryHasInstance nodes.

[turbofan] Constant-fold certain JSOrdinaryHasInstance nodes.

Move JSOrdinaryHasInstance lowering to JSNativeContextSpecialization,
which was previously mostly done in JSTypedLowering (for no reason).
Add new logic to the lowering to constant-fold OrdinaryHasInstance
checks when the map of the left-hand side and the "prototype" of the
right-hand side is known. This address the performance issue with the
(base) class constructors generated by Babel, i.e.:

  function _classCallCheck(instance, Constructor) {
    if (!(instance instanceof Constructor)) {
      throw new TypeError("Cannot call a class as a function");
    }
  }

  var C = function C() { _classCallCheck(this, C); };

for

  class C {}

Also ensure that a known constructor being used inside an instanceof
get's a proper initial map on-demand.
