As preparation for changing `LineIterator` to work with `MemoryBufferRef`: - Add an `operator==` that uses buffer pointer identity to ensure two buffers are equivalent. - Split out `MemoryBufferRef.h`, to avoid polluting `LineIterator.h` includers with everything from `MemoryBuffer.h`. This also means moving the `MemoryBuffer` constructor to a source file. Differential Revision: https://reviews.llvm.org/D89279
