This reverts commit b8c821f4e276855e3c62d14d1e04263b562300d3.

Reason for revert: compile errors, e.g. https://ci.chromium.org/p/v8/builders/luci.v8.ci/V8%20Linux%20-%20builder/39320

Original change's description:
> Extract JSObject class from objects.cc
> 
> I extracted following class member functions to js-objects.cc
> * JSReceiver
> * JSObject
> * JSBoundFunction
> * JSFunction
> * JSGlobalObject
> * JSDate
> * JSMessageObject
> 
> Declaration of all above class are in js-objects.h.
> 
> I also moved AllocationSite::DigestTransitionFeedback used in JSObject::UpdateAllocationSite
> and ShouldConvertToSlowElements used in JSObject and JSArray
> 
> This patch makes compile time of objects.cc from 17.6s to 14.1s on Z840 Linux.
> And js-objects.cc takes 8.69s for compile.
