Alexandre Ganea 4710865de9 [CodeView] Fix cycles in debug info when merging Types with global hashes ... When type streams with forward references were merged using GHashes, cycles were introduced in the debug info. This was caused by GlobalTypeTableBuilder::insertRecordAs() not inserting the record on the second pass, thus yielding an empty ArrayRef at that record slot. Later on, upon PDB emission, TpiStreamBuilder::commit() would skip that empty record, thus offseting all indices that came after in the stream. This solution comes in two steps: 1. Fix the hash calculation, by doing a multiple-step resolution, iff there are forward references in the input stream. 2. Fix merge by resolving with multiple passes, therefore moving records with forward references at the end of the stream. This patch also adds support for llvm-readoj --codeview-ghash. Finally, fix dumpCodeViewMergedTypes() which previously could reference deleted memory.
