Marco Bubke 5e0b207a89 Clang: Improve locking of string cache ...

The string cache is only very seldom written but very often read. To
improve thread scaling it is faster to lock it only for write operations.
So we use a shared mutex which is locked in shared mode for read
operations and locked exclusively for write operations.
