+
+Stack information is thread-specific and, until now, it was stored in a
+field in ThreadLocalTop. This CL moves stack information to the isolate
+and makes sure to update the stack start whenever a main thread enters
+the isolate. At the same time, the Stack object is refactored and
+simplified.
+
+As a side effect, after removing the Stack object, ThreadLocalTop
+satisfies the std::standard_layout trait; this fixes some issues
+observed with different C++ compilers.
