Each instruction carries its own PC by this point, so it just duplicates the PC of the first item in the vector. Moreover, when including a pending straddle at the head, the PC value was not set to the previous half's, ie PC-2. We keep pred_next_pc as that's used to determine where the bundle is predicted to go next, and the duplication avoids having to dynamically index the vector based on the number of instructions fed to decode.
