I think the fact that all of our options *must* have a short version is a 
pretty serious deficiency in our option parsing system. It results in a lot of 
unintuitive options that nobody uses because they can't guess what they stand 
for. But anyway, `-x` seems as good as any, as all the good alternatives are 
already taken.

For testing this, I think the best option would be something similar to the 
gdb-client suite (test/testcases/functionalities/gdb_remote_client), which 
allows you to mock the remote end of a connection. It is currently geared 
toward talking to the gdb server (and not the platform), but as the underlying 
protocol is the same, I am hoping that it can be repurposed to this use case 
fairly easily. I am imagining a flow where you create a mock server, configure 
it to respond appropriately to any packet that lldb issues, and then run e.g. 
"platform select remote-linux", "platform connect connect://localhost:%d", 
"platform proces list --all-users".

Setting that up is a bit overkill for a simple patch as this one, but as it 
looks like you're going to be doing a lot of work in this area in the near 
future, I think it makes sense to set up some testing infrastructure early.
