Summary: This commit removes the concrete_frame_idx member from NativeRegisterContext and related functions, which was always set to zero and never used. I also change the native thread class to store a NativeRegisterContext as a unique_ptr (documenting the ownership) and make sure it is always initialized (most of the code was already blindly dereferencing the register context pointer, assuming it would always be present -- this makes its treatment consistent).
