Add a new serializer, using a binary format based on the LLVM bitstream format. This format provides a way to serialize the remarks in two modes: 1) Separate mode: the metadata is separate from the remark entries. 2) Standalone mode: the metadata and the remark entries are in the same file. The format contains: * a meta block: container version, container type, string table, external file path, remark version * a remark block: type, remark name, pass name, function name, debug file, debug line, debug column, hotness, arguments (key, value, debug file, debug line, debug column) A string table is required for this format, which will be dumped in the meta block to be consumed before parsing the remark blocks. On clang itself, we noticed a size reduction of 13.4x compared to YAML, and a compile-time reduction of between 1.7% and 3.5% on CTMark.
