ok, headers in `libc/src/__support/math/tanhf16.h` have maintained alphabetical order now; `libc/src/__support/math/CMakeLists.txt` mimic header's order;

BTY, some target in `libc/src/__support/math/CMakeLists.txt` is different from `libc/src/__support/math/tanhf16.h`

example:

headers: 
```
#include "src/__support/FPUtil/FEnvImpl.h"
```

cmake:
```
libc.src.__support.FPUtil.polyeval
```

so their alphabetical order is different; I keep cmake's dep order same as headers.

deps in bazel have re-order by alphabetical order .
