ftrace: rename unlikely iter_ctrl to branch

Impact: rename of iter_ctrl unlikely to branch

The unlikely name is ugly. This patch converts the iter_ctrl command
"unlikely" and "nounlikely" to "branch" and "nobranch" respectively.

It also renames a lot of internal functions to use "branch" instead
of "unlikely".
