Rename DR_ALIGNED_TO to DR_OFFSET_ALIGNMENT
This patch renames DR_ALIGNED_TO to DR_OFFSET_ALIGNMENT, to avoid
confusion with the upcoming DR_BASE_ALIGNMENT. Nothing needed the
value as a tree, and the value is clipped to BIGGEST_ALIGNMENT
(maybe it should be MAX_OFILE_ALIGNMENT?) so we might as well use
an unsigned int instead.
