We have need to reuse this functionality, including making additional generic stream types that are smarter about how and when they copy memory versus referencing the original memory. So all of these structures belong in the common library rather than being pdb specific. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@270751 91177308-0d34-0410-b5e6-96231b3b80d8
