GetOutputStream() owns the stream it returns pointer to and the pointer should never be freed by us. When we fail to load and exit early, unique_ptr still holds the pointer and frees it which leads to compiler crash when CompilerInstance attempts to free it again. Added regression test for failed bitcode linking. Differential Revision: http://reviews.llvm.org/D9625 llvm-svn: 237159
