-dnl  AMD64 mpn_addlsh_n and mpn_rsblsh_n.  R = V2^k +- U.
-dnl  ("rsb" means reversed subtract, name mandated by mpn_sublsh1_n which
-dnl  subtacts the shifted operand from the unshifted operand.)

-C K8,K9:	 3.25	(mpn_lshift + mpn_add_n costs about 4.1 c/l)
-C K10:		 3.25	(mpn_lshift + mpn_add_n costs about 4.1 c/l)
-C P4:		14
-C P6-15:	 4

-C This was written quickly and not optimized at all.  Surely one could get
-C closer to 3 c/l or perhaps even under 3 c/l.  Ideas:
-C   1) Use indexing to save the 3 LEA
-C   2) Write reasonable feed-in code
-C   3) Be more clever about register usage
-C   4) Unroll more, handling CL negation, carry save/restore cost much now
-C   5) Reschedule
