  Log Message:
  -----------
  [CMake] Add detection for the mold linker in AddLLVM.cmake.

mold says it is compatible with GNU ld and gold linkers:

```
$ mold -v
mold 0.9.5 (compatible with GNU ld and GNU gold)
```

And thus it currently gets detected as Gold.

With the following diff, CMake now correctly reports the linker name, and mold keeps being identified as Gold internally for now.
