Build fix for the latest LLVMContext changes (LLVM r75445) This shouldn't break the build with older LLVM revs. We include LLVMContext.h in gen/llvm.h now to make the transition a little bit easier.

module tangotests.mem2;

void main()
{
    int* ip = new int;
    assert(*ip == 0);
    *ip = 4;
    assert(*ip == 4);
    delete ip;
    assert(ip is null);
}
