a debug session with only a remote path to the file you are debugging using the SB API's. This patch makes it possible to do this using target create --remote-file <some_path> without supplying a local file as well. Prior to this change we errored out saying that we haven't implemented copying the binary back from the remote. I didn't implement the copy back (in the case I'm interested in - iOS debugging - we don't actually have a way for lldb to do that). This patch doesn't impede doing that, I just didn't need it. I think for some object file formats debugging w/o the binary file is hard because of what doesn't get mapped in. I didn't try to arbitrate that, I'm assuming anybody who has to do this knows what they are going to get. If there's a connected platform that can check that the remote file exists, it will do so, otherwise we trust the user's input - if it isn't there the process launch is going to fail with no-such-file so it will be pretty clear what went wrong.
