DebugInfo: Use DWP cu_index to speed up symbolizing (as intended)
I was a bit lazy when I first implemented this & skipped the index
lookup - obviously for large files this becomes pretty crucial, so here
we go, do the index lookup. Speeds up large DWP symbolizing by... lots.
(20m -> 20s, actually, maybe more in a release build (that was a release
build without index lookup, compared to a debug/non-release build with
the index usage))
