CallIC and CallConstructStub look so alike, at least in the feedback they gather even if the implementation differs...and CallIC has such a nice way of surfacing the feedback (CallICNexus), that there is a request to make CallConstructStub look analogous. Enter ConstructICStub.

This is the initial support for binary operation hints on javascript
binary operators, i.e. JSAdd, JSSubtract and so on. The hints are
extracted from the fullcodegen code object before graph building and the
AstGraphBuilder puts those hints on the operators if available.

Port 47502a23

Original commit message:
    Previously all contexts had a link to the global object, but what is
    required in most cases (except for the global load, store and delete
    case) is the native context.

    This also removes the second dummy global object that was still linked
    to every native context. We will add a different mechanism to ensure
    that builtins do not pollute the actual global object during
    bootstrapping.

    Drive-by-fix: Unify some MacroAssembler magic and drop obsolete stuff.
