page-flags: move code around
The preparation patch: we are going to use compound_head(), PageTail()
and PageCompound() to define page-flags helpers.
Let's define them before macros.
We cannot user PageHead() helper in PageCompound() as it's not yet
defined -- use test_bit(PG_head, &page->flags) instead.
