[LLVMdev] store addrspace qualifier

[Mon Ping Wang]

The address qualifier is stored in the type of %result.  From that  
operand, you can get the Value and then call getType.  The type for  
result  should be a PointerType which you cast to a PointerType and  
get the getAddressSpace e.g. cast<PointerType>(Ty)->getAddressSpace()
