> The AOT stub blob save and restore API handles Adapter blobs differently to other single-stub blobs by passing the associated entries in a separate auxiliary array. Storing the entry offsets in the blob, as happens with other generated blobs, simplifies the current save/restore API and implementation. It also makes it easier to define and implement an API extension supporting save and restore of multi-stub (StubGen) blobs.

Testing: tier1 + runtime/cds/appcds

@ashu-mehra @vnkozlov could you review this cleanup?
