Yet another fix for finding llvm's config file. Since llvm-config --includedir sometimes includes the trailing llvm/ and sometimes it doesn't, we just check both directories.

module bug8;

void main()
{
    s = newS();
}

S* s;

struct S
{
    int i;
}

S* newS()
{
    auto tmp = new S;
    tmp.i = 4;
    return tmp;
}
