Force initialize the runtime module in Module::genLLVMModule. It is required for all non-trivial D modules anyway, so why load it lazily? This fixes run/typeid_83.d (DtoDeclareTypeInfo expects runtime to be initialized)

module cond1;

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