Mark destination buffer in zlib::compress and zlib::decompress as fully initialized. When building LLVM with system zlib and MemorySanitizer instrumentation, MSan does not observe memory writes in zlib code and erroneously considers zlib output buffers as uninitialized, resulting in false use-of-uninitialized memory reports. This change helps MSan understand the state of that memory and prevents such reports. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@222763 91177308-0d34-0410-b5e6-96231b3b80d8
