Zachary Turner af5c5622dd Speed up iteration of CodeView record streams. ...

There's some abstraction overhead in the underlying
mechanisms that were being used, and it was leading to an

showed up on a profile.  Eliminating this and going back to
a low-level byte-based implementation speeds up lld with
/DEBUG between 10 and 15%.
