Subject: rtl.h (mem_attrs): Rename decl to expr; adjust all users.

        * rtl.h (mem_attrs): Rename decl to expr; adjust all users.
        (MEM_EXPR): Rename from MEM_DECL; adjust all users.
        * emit-rtl.c (set_mem_expr): Rename from set_mem_decl.
        * expr.h, final.c, reload1.c: Adjust users.

        * alias.c (nonoverlapping_component_refs_p): New.
        (decl_for_component_ref, adjust_offset_for_component_ref): New.
        (nonoverlapping_memrefs_p): Use them.
        * emit-rtl.c (component_ref_for_mem_expr): New.
        (set_mem_attributes): Use it.
        (set_mem_offset): New.
        * expr.c (expand_assignment): Call set_mem_attributes for
        inner references; adjust the memory offset as needed.
        * print-rtl.c (print_mem_expr): New.
        (print_rtx): Use it.
