Restructure tests/benchmarks directory.

We follow the same structure as used in the src directory. This makes it
easier to navigate through the jungel, especially now that we are going
to add functional tests etc.

-    \since 4.5
-    \class QFileSystemIterator
-    \brief The QFileSystemIterator class provides an iterator for directory entrylists.
-
-    You can use QFileSystemIterator to navigate entries of a directory one at a time.
-    It is similar to QDir::entryList() and QDir::entryInfoList(), but because
-    it lists entries one at a time instead of all at once, it scales better
-    and is more suitable for large directories. It also supports listing
-    directory contents recursively, and following symbolic links. Unlike
-    QDir::entryList(), QFileSystemIterator does not support sorting.
-
-    The QFileSystemIterator constructor takes a QDir or a directory as
-    argument. After construction, the iterator is located before the first
-    directory entry. Here's how to iterate over all the entries sequentially:
-
-    \snippet doc/src/snippets/code/src.corelib.io.qdiriterator.cpp 0
-
-    The next() function returns the path to the next directory entry and
-    advances the iterator. You can also call filePath() to get the current
-    file path without advancing the iterator.  The fileName() function returns
-    only the name of the file, similar to how QDir::entryList() works. You can
-    also call fileInfo() to get a QFileInfo for the current entry.
-
-    Unlike Qt's container iterators, QFileSystemIterator is uni-directional (i.e.,
-    you cannot iterate directories in reverse order) and does not allow random
-    access.
-
-    QFileSystemIterator works with all supported file engines, and is implemented
-    using QAbstractFileEngineIterator.
-
-    \sa QDir, QDir::entryList(), QAbstractFileEngineIterator
-*/
-
-/*! \enum QFileSystemIterator::IteratorFlag
-
-    This enum describes flags that you can combine to configure the behavior
-    of QFileSystemIterator.
-
-    \value NoIteratorFlags The default value, representing no flags. The
-    iterator will return entries for the assigned path.
-
-    \value Subdirectories List entries inside all subdirectories as well.
-
-    \value FollowSymlinks When combined with Subdirectories, this flag
-    enables iterating through all subdirectories of the assigned path,
-    following all symbolic links. Symbolic link loops (e.g., "link" => "." or
-    "link" => "..") are automatically detected and ignored.
