Since r241097, `DIBuilder` has only created distinct `DICompileUnit`s. The backend is liable to start relying on that (if it hasn't already), so make uniquable `DICompileUnit`s illegal and automatically upgrade old bitcode. This is a nice cleanup, since we can remove an unnecessary `DenseSet` (and the associated uniquing info) from `LLVMContextImpl`. Almost all the testcases were updated with this script: git grep -e '= !DICompileUnit' -l -- test | grep -v test/Bitcode | xargs sed -i '' -e 's,= !DICompileUnit,= distinct !DICompileUnit,' I imagine something similar should work for out-of-tree testcases. llvm-svn: 243885
