The number is irrelevant and may differ by architecture. We are only
interested if it happened or not

047963922c MDEV-9736: Window functions: multiple cursors to read filesort result
Add support for having multiple IO_CACHEs with type=READ_CACHE to share
the file they are reading from.
Each IO_CACHE keeps its own in-memory buffer. When doing a read or seek
operation on the file, it notifies other IO_CACHEs that the file position
has been changed.

Make Rowid_seq_cursor use cloned IO_CACHE when reading filesort result.
