I would make these one-liners:

void SetData(void* data) { embedder_data_ = data; }
void* GetData() { return embedder_data_; } 

+    embedder_data_ = data;
+  }
+  void* GetData() {
+    return embedder_data_;

   class ThreadDataTable {
    public:
     ThreadDataTable();
     ~ThreadDataTable();
