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 cond1;

void main()
{
    double a = 2;
    double b = 4;
    double c = (a > 0) ? a : b;
}
