`Construct.FunctionsWithSameAddress` started failing at ff5892c5. It
looks like the cause of this is in the calls to
`generate_duplicate_function`:
```
generate_duplicate_function("_without_form");
generate_duplicate_function("_and_void");
```
`generate_duplicate_function` directly calls `new
Module::Function(...);`, which stores the `StringView` it's given.
`generate_duplicate_function` currently takes a `const
string &`; in the above statements, these strings get `free()`d at the
`;`.
Making the parameter a `StringView` means the `Module::Function` will
store pointers to the string literal, which lives for the whole program.
All calls to `generate_duplicate_function` are given literals.
