* version.c: Bump for snapshot.

        * expmed.c (expand_divmod): Make op1_is_pow2 depend on unsignedp
        for negative constants.  Promote EXACT_DIV_EXPR to TRUNC_DIV_EXPR
        when op1_is_pow2.

        * final.c (shorten_branches): During first pass, assume worst
        possible alignment for ADDR_VEC and ADDR_VEC_DIFF insns.

        * Makefile.in (distclean): Remove various things left around
        by running the testsuite.
