[opaque pointer type] Pass the explicit call type when creating calls from LazyRuntimeFunctions

The implicit conversion was causing issues for a helper being added that
would take an llvm::Function rather than an llvm::Value to make the
CallInst. Since we'll eventually need to specify the type of the call
explicitly anyway, fix these up to avoid the future ambiguity.
