jump_label: Do not profile branch annotations
While running my branch profiler that checks for incorrect "likely" and "unlikely"s around the kernel, there's a large number of them that are incorrect due to being "static_branches". As static_branches are rather special, as they are likely or unlikely for other reasons than normal annotations are used for, there's no reason to have them be profiled. Expose the "unlikely_notrace" and "likely_notrace" so that the static_branch can use them, and have them be ignored by the branch profilers.
