(lra_emit_add, lra_emit_move): Ditto.
* lra-constraints.c (in_class_p): Add check for move for a new
insn.
(change_class): Rename to lra_change_class. Move to lra-int.h.
(get_reload_reg, narrow_reload_pseudo_class): Adjust calls of
change_class.
(process_addr_reg, process_addr): Ditto.
(curr_insn_transform): Ditto. Add check on old pseudo for
optional reload.
