page-flags: define behavior of FS/IO-related flags on compound pages
It seems we don't have compound page on FS/IO path currently. Use
PF_NO_COMPOUND to catch if we have.
The odd exception is PG_dirty: sound uses compound pages and maps them
with PTEs. PF_NO_COMPOUND triggers VM_BUG_ON() in set_page_dirty() on
handling shared fault. Let's use PF_HEAD for PG_dirty.
