Owning the buffer is somewhat inflexible. Some Binaries have sub Binaries (like Archive) and we had to create dummy buffers just to handle that. It is also a bad fit for IRObjectFile where the Module wants to own the buffer too. Keeping this ownership would make supporting IR inside native objects particularly painful. This patch focuses in lib/Object. If something elsewhere used to own an Binary, now it also owns a MemoryBuffer. This patch introduces a few new types. * MemoryBufferRef. This is just a pair of StringRefs for the data and name. This is to MemoryBuffer as StringRef is to std::string. * OwningBinary. A combination of Binary and a MemoryBuffer. This is needed for convenience functions that take a filename and return both the buffer and the Binary using that buffer. The C api now uses OwningBinary to avoid any change in semantics. I will start a new thread to see if we want to change it and how. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@216002 91177308-0d34-0410-b5e6-96231b3b80d8
