v8/src/contexts-inl.h
mstarzinger 5f57ebe222 Make isolate.h usable without objects-inl.h header.
This CL us a pure refactoring that makes an empty compilation unit
including just "isolate.h" or "contexts.h" but not "objects-inl.h"
compile without warnings or errors. This is needed to further reduce
the header dependency tangle.
