MISRA C:2012 Rule 2.1 states: "A project shall not contain unreachable code".
As such, this series eliminates various instances of unreachable code found in
Xen, by providing equivalent compliant constructs.

This series is loosely based on my earlier series [1], but the overall approach
has changed since; for instance, declarations without initialization are now
ignored, as detailed in docs/misra/deviations.rst.
