Manman Ren ea5d96e1cf DIBuilder: retain a type when created with a unique identifier. ... createClassType, createStructType, createUnionType, createEnumerationType, and createForwardDecl will retain a type when created with a unique identifier, to make sure they are treated as used even when all uses are replaced with the identifiers. Use TrackingVH<MDNode> instead of MDNode in AllRetainTypes, since the created node can later be updated. The change will be tested when clients of DIBuilder start to pass in non-empty unique identifier. llvm-svn: 189621		2013-08-29 23:17:54 +00:00
