The dyld_all_image_infos structure, at version 13 and higher, has
a UUID for the shared cache libraries that can be used to confirm
that one process' shared cache is the same as another, or that a
process' in-memory shared cache is a match for a given on-disk
dyld_shared_cache binary file.  Use these UUIDs to catch some
uncommon problems when the shared caches are being changed for debug
purposes.
