        * lambda-code.c (replace_uses_equiv_to_x_with_y): Add YINIT,
        REPLACEMENTS, FIRSTBSI arguments.  If initial condition or
        type is different between Y and USE, create a temporary
        variable, initialize it at the beginning of the body bb
        and use it as replacement instead of Y.
