cpu: Proposal for changing the indirect branch predictor interface
Now the indirect branch predictor handles its own GHR instead of getting
the one from the direction predictor.
Also, now the commit method of the indirect predictor is called for every
pending branch on an update, as the indirect predictors may want to update
their interal structures/histories with the information of each branch.
