        * tree.h (get_object_alignment): Declare.
        * emit-rtl.c (set_mem_attributes_minus_bitpos): Call
        get_object_alignment if needed.
        * builtins.c (get_pointer_alignment): Move ADDR_EXPR operand handling
        to ...
        (get_object_alignment): ... here.  New function.  Try harder to
        determine alignment from get_inner_reference returned offset.
