Now that we're using LLVM 2.5, we can stop always running the CFGSimplification pass. The pass was originally added as a workaround for a LLVM 2.4 bug where debug info would reference labels that have been optimized away.

module bug38;

void func(int* p)
{
    p++;
}

void main()
{
    int i;
    func(&i);
}
