There doesn't seem to be any special flag but they all have the attribute of having a start and end SourceLocation that are the same. Really I'm trying to identify the VarDecl the user actual wrote in code so I want to filter out the auto-generated ones.

Probably VD->isImplicit().  Implicit bit is set in SemaStmt.cpp,
BuildForRangeVarDecl().
