-// Every pointer in a frame has a slot id. On 32-bit platforms, doubles consume
-// two slots.
-//
-// Stack slot indices >= 0 access the callee stack with slot 0 corresponding to
-// the callee's saved return address and 1 corresponding to the saved frame
-// pointer. Some frames have additional information stored in the fixed header,
-// for example JSFunctions store the function context and marker in the fixed
-// header, with slot index 2 corresponding to the current function context and 3
-// corresponding to the frame marker/JSFunction.
