I don't think that powerful enough; it requires the same destination
registers:

	      /* Try to transform (set (REGX) (CONST_INT A))
				  ...
				  (set (REGX) (CONST_INT B))
		 to
				  (set (REGX) (CONST_INT A))
				  ...
				  (set (REGX) (plus (REGX) (CONST_INT B-A)))

I think you really need the Joern's optmize_related_values patch.  Also see
PR33699.
