Log:
        PR bootstrap/39454
        * cse.c (fold_rtx): Don't modify original const_arg1 when
        canonicalizing SHIFT_COUNT_TRUNCATED shift count, do it on a
        separate variable instead.
        * rtlanal.c (nonzero_bits1) <case ASHIFTRT>: Don't assume anything
        from out of range shift counts.
        (num_sign_bit_copies1) <case ASHIFTRT, case ASHIFT>: Similarly.
