[Bug target/15425] New: 128-bit division do not work

["hebisch at math dot uni dot wroc dot pl" <gcc-bugzilla at gcc dot gnu dot org>]

The follwing program compiled by:
 ../gcc/xgcc -B../gcc tess_div.c
gives me:
$ ./a.out
6341068292483973050
the program:
#include <stdio.h>

int main(void)
{
        typedef int myi128 __attribute__ ((mode(TI)));
        myi128 x=0;
        myi128 y=32;
        long z=x/y;
        printf("%ld\n", z);
        return 0;
}

AFAIKS the arguments to `__divti3' function are passed incorrectly.
The problem affects GNU Pascal. Namely, gpc uses `bitsizetype' to
do adress calculation for packed arrays. On 64-bit targets 
`bitsizetype' is done with 128-bit precision. Since on x86_64
such arithmetic does not work (with 3.3.3 backend) it makes
packed arrays unusable ont that target.
