Are those two tests exactly the same except the compiler flags? If so, let's turn this into a `.sh.pass.cpp` and then do:

```
// RUN: %{build} -fsigned-char
// RUN: %{run}

// RUN: %{build} -funsigned-char
// RUN: %{run}
```

And while we're at it we should probably also do

```
// RUN: %{build}
// RUN: %{run}
```

Then we can have a single test file.
