UseListOrder: Order GlobalValue uses after initializers

To avoid unnecessary forward references, the reader doesn't process
initializers of `GlobalValue`s until after the constant pool has been
processed, and then in reverse order.  Model this when predicting
use-list order.  This gets two more Bitcode tests passing with
`llvm-uselistorder`.

Part of PR5680.
