Here we introduce the `Backtraces` type and associated machinery for
attaching these via `ExceptionContext`. These has a few compile-time
regressions (`T15703` and `T9872d`) due to the additional dependencies
in the exception machinery.
As well, there is a surprisingly large regression in the
`size_hello_artifact` test. This appears to be due to various `Integer` and
`Read` bits now being reachable at link-time. I believe it should be
possible to avoid this but I have accepted the change for now to get the
feature merged.

Most GhcExceptions are user-facing errors and therefore the
ExceptionContext has little value. Ideally we would enable
it in the DEBUG compiler but I am leaving this for future work.
