After the open+fstat optimization, files were already opened for FileManager::getBufferForFile() and we closed them after reading them.
The problem was that when -working-directory was passed, the code path that actually reuses & closes the already opened file descriptor
was not followed.

This patch is a big refactoring of llvm-diff. It doesn't add new features, but it re-organizes the old features, so I can insert the MetadataEngine to use the same infrastructure.
