emit-rtl.c (set_mem_attributes_minus_bitpos): Rename from set_mem_attributes and add BITPOS argument.

        * emit-rtl.c (set_mem_attributes_minus_bitpos): Rename from
        set_mem_attributes and add BITPOS argument.  Subtract it from
        OFFSET when same is adjusted.
        (set_mem_attributes): New wrapper function.
        * expr.c (expand_assignment): Use set_mem_attributes_minus_bitpos;
        remove offset adjustment hack.
        * expr.h (set_mem_attributes_minus_bitpos): Declare.
