In preparation for moving to llvm's opaque pointer representation replace getPointerElementType and CreateCall/CreateLoad/Store uses that dependent on the address operand's pointer element type. This means an `Address` carries the element type and we use `FunctionPointer` in more places or read the function type off the `llvm::Function`.
