17e226f7 - [lldb] Fix crash when passing a folder in as the executable (#175181)

[lldb] Fix crash when passing a folder in as the executable (#175181) This is another instance where we weren't checking that the result of FileSystem::CreateDataBuffer and unconditionally accessing it, similar to the bug in SourceManager last week. In this particular case, ObjectFile was assuming that we can read the contents non-zero, which isn't true for directory nodes. Jim figured this one out yesterday. I'm just putting up the patch and adding a test. rdar://167796036
