[PATCH 06/32] read-cache: store in-memory flags in the first 12 bits of ce_flags

We're running out of room for in-memory flags. But since b60e188 (Strip namelen out of ce_flags into a ce_namelen field - 2012-07-11), we copy the namelen (first 12 bits) to ce_namelen field. So those bits are free to use. Just make sure we do not accidentally write any in-memory flags back.
