[Bug tree-optimization/36116] ICE with -O2 -ftree-loop-distribution -funsafe-loop-optimizations -m32

Instead of a segfault I see a crash in fold_binary, at fold-const.c:9278

Reduced testcase that crashes already with "-O -ftree-loop-distribution":

==========================================
extern void *malloc (__SIZE_TYPE__ n);

void foo()
{
  char *p, *q;
  int i;

  p = malloc(8);
  q = malloc(8);

  for (i = 0; i < 8; i += 2)
  {
    p[i >> 1] = 0;
    q[i >> 1] = 0;
  }
}
==========================================

Apparently this has been fixed with the patch for PR38250.
