// An InstanceStackChunkKlass is a specialization of the InstanceKlass.
//
// The stackChunkOops have a header containing metadata, and a blob containing a
// stack segment (some integral number of stack frames).
//
// A chunk is said to be "mixed" if it contains interpreter frames or stubs
// (which can only be a safepoint stub as the topmost frame). Otherwise, it
// must contain only compiled Java frames.
//
// Interpreter frames in chunks have their internal pointers converted to
// relative offsets from fp. Derived pointers in compiled frames might also
// be converted to relative offsets from their base.
