* reload.h (elimination_target_reg_p): Declare.
* reload.c (find_reloads): Don't apply the reg_rtx move
optimization if the SET_DEST satisfies elimination_target_reg_p.
* reload1.c (elimination_target_reg_p): New function.
(gen_reload): In the move/add2 fallback, make sure that op0
does not overlap the destination register.
