The explanation is quite simple. LLVM understand C and C++ 
runtime. It doesn't understand D runtime (LDC is doing some work 
in that regard, but it is still limited). So you see a difference 
between C and C++ as some optimization will be done in C/C++ (for 
instance heap to stack promotion) when it won't be done in D.

Haskell has really different semantic than C and C++, and quite 
far away from the hardware, so you have to expect a performance 
drop. The comparison of either C or C++ with haskell is not 
really meaningful as it is really comparing apple and bananas.
