tree-ssa-loop-ivopts.c: Include target.h. 

* tree-ssa-loop-ivopts.c: Include target.h.
        (produce_memory_decl_rtl): Pass the rtx through encode_section_info.
        (get_address_cost): Force SYMBOL_FLAG_LOCAL set.
        (force_expr_to_var_cost): Use produce_memory_decl_rtl.
        * Makefile.in (tree-ssa-loop-ivopts.o): Depend on TARGET_H.
