nit: Let's call the file "liveedit-frame-drop-mode.h" without the first hyphen
to be consistent with everything else.

Also, the file should be added to BUILD.gn and v8.gyp I think.

Alternatively, could we just add this enum do globals.h and call it a day? It's
a little bit less clean but avoids the additional file. Just a suggestion.

Moved to globals.h

+#define V8_DEBUG_LIVEEDIT_FRAME_DROP_MODE_H_
+
+namespace v8 {
+namespace internal {
+
+// Describes how exactly a frame has been dropped from stack.
+enum LiveEditFrameDropMode {
+  // No frame has been dropped.
+  LIVE_EDIT_FRAMES_UNTOUCHED,
+  // The top JS frame had been calling debug break slot stub. Patch the
+  // address this stub jumps to in the end.
+  LIVE_EDIT_FRAME_DROPPED_IN_DEBUG_SLOT_CALL,

+  LIVE_EDIT_FRAME_DROPPED_IN_DIRECT_CALL,
