This flag causes all files that were read by the compilation to be embedded into a produced module file. This is useful for distributed build systems that use an include scanning system to determine which files are "needed" by a compilation, and only provide those files to remote compilation workers. Since using a module can require any file that is part of that module (or anything it transitively includes), files that are not found by an include scanner can be required in a regular build using explicit modules. With this flag, only files that are actually referenced by transitively-#included files are required to be present on the build machine. llvm-svn: 253950
