mm: rename the 'compound_head' field in the 'struct page' to 'compound_info'
The 'compound_head' field in the 'struct page' encodes whether the page is
a tail and where to locate the head page. Bit 0 is set if the page is a
tail, and the remaining bits in the field point to the head page.
As preparation for changing how the field encodes information about the
head page, rename the field to 'compound_info'.
