[LLVMdev] Insert a function call in the code

try removing the second Type::getVoidTy.  Your function doesn't take any
parameters, so you should simply pass an empty list of parameter types.
Unlike in C++, a function foo(void) taking no parameters shouldn't be
declared as taking one parameter of void type, it takes no parameters.

Ciao, Duncan.
