No any changes, will follow up with D28807 commit containing APLi change for clang to fix build issues happened. Original commit message: [Support/Compression] - Change zlib API to return Error instead of custom status. Previously API returned custom enum values. Patch changes it to return Error with string description. That should help users to report errors in universal way. Differential revision: https://reviews.llvm.org/D28684 llvm-svn: 292226
