The attached patch simplifies a few interfaces that don't need to take ownership of a buffer. For example, both parseAssembly and parseBitcodeFile will parse the entire buffer before returning. There is no need to take ownership. Using a MemoryBufferRef makes it obvious in the type signature that there is no ownership transfer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@216488 91177308-0d34-0410-b5e6-96231b3b80d8
