x86: re-arrange struct page_info members

By combining the overlay fields that are 8 bytes long (on x86-64) into
a union separate from the one used for the 4 byte wide fields, no
unnecessary padding will be inserted while at the same time avoiding
to use __attribute__((__packed__)) on any of the sub-structures (which
risks misaligning structure members without immediately noticing).
