NFC: Change all helper functions in `tuple_ops` not to require `llvm::Module` argument, as it can be derived from the already provided `llvm::IRBuilder`.
This makes functions easier to code and the calls less verbose, and additionally enables making calls from helper classes where `llvm::Module*` might not be available.
