This was reverted several times due to what ultimately turned out to be incompatibilities in our serialized hash table format. Several changes went in prior to this to fix those issues since they were more fundamental and independent of supporting injected sources, so now that those are fixed this change should hopefully pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@328363 91177308-0d34-0410-b5e6-96231b3b80d8
