combine.c (num_sign_bit_copies): In NEG...

        * combine.c (num_sign_bit_copies): In NEG, MULT, DIV and MOD cases,
        when a test can't be performed due to limited width of
        HOST_BITS_PER_WIDE_INT, use the more conservative approximation.
        Fix UDIV case for cases where the first operand has the highest bit
        set.
