Separately track text and data segments for ownsAddress. We were previously tracking one range per image, encompassing the range from the start of the image through the end of the data segment. This ends up including a lot of unwanted address space if the two aren't adjacent, as is the case for libraries in the shared cache on Darwin. This makes metadataIsActor a lot more reliable, as it was previously identifying a lot of garbage as actor metadata due to the supposed descriptor pointer falling in this range. rdar://113417637
