	config/{sparc/tm-sparc.h,pyr/tm-pyr.h,vax/tm-vax.h}: Remove field
	next_frame from struct frame_info.  It has no purpose beyond

If there is a frame below this one, and the frame pointers are
identical, it's a leaf frame and the bottoms are the same also.

Otherwise the bottom of this frame is the top of the next frame.
The bottom field is misnamed, since it might imply that memory from
bottom to frame contains this frame. That need not be true if
stack frames are allocated in different segments (e.g. some on a
stack, some on a heap in the data segment). */
