$ llvm-gcc -emit-llvm -c t2.i -o t2.bc
WARNING: 128-bit integers not supported!

Reduced test case follows, I don't see any 128-bit integers there:
[original testcase from linux kernel mm/slub.c, reduced using delta]

$ cat t2.i
     struct kmem_cache {
     int objects;
     static void process_slab( struct kmem_cache *s   ) {
     unsigned long map[(((s->objects) + (64) - 1) / (64))];
