llvm-mirror/tools/lto/LTOCodeGenerator.h
Dan Gohman f9e09104f1 Make tool_output_file's raw_ostream instance a member variable instead
of a base class.

This makes it possible to unregister the file from FilesToRemove when
the file is done. Also, this eliminates the need for
formatted_tool_output_file.
