[Bug tree-optimization/44503] "control flow in the middle of basic block" with -fprefetch-loop-arrays

Actually, the prefetching is for the following loop:
    for (i = 0; i < p[2]; i++)
      q[i] = 0;

I do not understand why unrolling of this loop affects other part of
the program that has longjmp.
