Summary:
This cleans up the now unnecessary debug info collection in CoroSplit.
This makes CoroSplit pass almost as fast with -g2 as it is with -g1 on
the sample cpp file used with other parts of this stack:
| | Baseline | IdentityMD set | Prebuilt CommonDI | MetadataPred (cur) |
|-----------------|----------|----------------|-------------------|--------------------|
| CoroSplitPass | 306ms | 221ms | 68ms | 3.8ms |
| CoroCloner | 101ms | 72ms | 0.5ms | 0.5ms |
| CollectCommonDI | - | - | 63ms | - |
| Speed up | 1x | 1.4x | 4.5x | 80x |
