dynamic_debug: add jump label support
...
Although dynamic debug is often only used for debug builds, sometimes
its enabled for production builds as well. Minimize its impact by using
jump labels. This reduces the text section by 7000+ bytes in the kernel
image below. It does increase data, but this should only be referenced
when changing the direction of the branches, and hence usually not in
cache.
