Attach the cleanup to the `Temporary` instruction instead of to the `TemporaryStorage` instruction. We create `TemporaryStorage` instructions speculatively when creating an initializing expression, and may overwrite those instructions with other instructions if it turns out that a temporary is not required. Instead, wait until we finalize the temporary and create a `Temporary` instruction to register the cleanup.
