class BranchPlugin extends ExecutionUnitElementSimple with LearnSource

Implement the branch/jump handeling in the execute stage. Depending if the CPU has a BTB it work completly differently. - If there is no BTB, then the plugin work very "normaly" and just execute the incoming instructions - If there is a BTB, then the goal of the plugin is to check if the predictions done were right, and correct if necessary

In the case there is multiple BranchPlugin on a given execution lane, they will share quite a bit of hardware via the PcCalc Area. Also, only the last instance of BranchPlugin on a given execution lane will feed the LearnPlugin via its LearnSource service. This reduce the hardware area aswell as reducing the possibility of multiple BranchPlugin providing LearnSource request at the same time.
