To simplify this, I'm going to keep the singular `getExceptionStream()` API, and then in the other patch remove that API + move LLDB to the new API.

It's just that they should be kept as small as possible. The thing I want to avoid is making a complex change to one project _and_ simultaneously make a complex change (depending on the first one) in the other project and putting both on the same review.

Appreciate it, my question was more for me to learn if there was any unforeseen issues I could run into either way. As I am still new to LLDB/LLVM I'm trying to absorb as much expertise as possible.
