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. R=bmeurer@chromium.org Review URL: https://codereview.chromium.org/1322883002 Cr-Commit-Position: refs/heads/master@{#30500}
