This reduces the amount of complexity around ThinLTO module buffers. It removes duplication between
ModuleBufferandThinBuffer(the latter was also used for fat LTO in some cases), clarifies when and where the ThinLTO summary is used (only for--emit thin-link-bitcode, ThinLTO performed by rustc rebuilds the summary every time). This also enables a follow up cleanup to reduce code duplication between red, green and imported codegen units.Part of rust-lang/compiler-team#908
