bmeurer a14f228188 [turbofan] Support fast access to the current global object. 
This is essentially a port of http://crrev.com/2403003002 to TurboFan,
adding support for fast access to JSGlobalObject properties through the
current native contexts' JSGlobalProxy.

It's a slightly bigger change, since JSNativeContextSpecialization and
JSGlobalObjectSpecialization needs merging for this to work, as due to
different type feedback layout we cannot just turn a JSLoadNamed into
JSLoadGlobal operator (and same for JSStoreNamed vs. JSStoreGlobal).
This part of the change is mostly mechanical.
