The following code snippet causes an ICE on mainline when compiled with
"-O -ftree-vectorize -funroll-loops":

=============================
void foo();

void bar()
{
    int i, j, k=0;

    for (i=0; i<2; ++i)
        if (j) k=2;

    if (k) foo();
}
=============================

bug.c: In function 'bar':
bug.c:4: internal compiler error: in do_jump, at dojump.c:274
Please submit a full bug report, [etc.]
