for each number, you create a corresponding ConstantInt using ConstantInt::get
   static Constant *get(Type *Ty, uint64_t V, bool isSigned = false);
(there are a bunch of other methods too).  Once you have them, you create the
array using ConstantArray::get
   static Constant *get(ArrayType *T, ArrayRef<Constant*> V);
Then you create the struct using ConstantStruct::get
   static Constant *get(StructType *T, ArrayRef<Constant*> V);

Ciao, Duncan.
