Imagine a multi-arch gdb with several arches having bounds registers.
How do we distinguish them in the pretty-printer namespace?

We could do something like that for 7.9 alright.
At the moment it feels like a bit of overkill just for one pretty-printer.
And for 7.8.1 I want to do something simple.
