ProcessLaunchInfo cannot be trivially moved to Utility (and indeed, in this patch, you are keeping it in Host), because it contains some references to Host-specific code (PTY stuff). Now, I am not convinced having the PTY class be a member of ProcessLaunchInfo is a good thing, but assuming we don't want to refactor that now, I think it might be better to keep Process(Launch)Info and friends in the same package (i.e., in Host), at least until we have a reason to do otherwise.
Well, the biggest difference between ProcessAttachInfo / ProcessLaunchInfo and the ones here is that those actually have some non-trivial functionality associated with them. It might be possible to decouple that functionality from the descriptions themselves, but it didn't seem worth it to me.
I have a mild preference for putting them in Utility on the grounds that logically that's where they seem to make the most sense. A Process could just as easily be running on a target as on the host, and we may want to pass this description around, and so favoring one or the other regarding to put them seemed a bit biased. We do already have a process class in Host called HostProcess, and that's more what I envision a host-specific process looking like. Low level methods that map directly to system calls to manipulate and query a process's state, etc.
As for D58167 <https://reviews.llvm.org/D58167>, I mostly just had a drive-by passing comment, and it looked fine to me after that, but I guess I was waiting for someone else to click Accept since my comment was fairly minor. But I'll go ahead and accept it anyway just to unblock
