cpu: Add an indirect branch target predictor
This patch adds a configurable indirect branch predictor that can be indexed by a combination of GHR and path history hashes. Implements the functionality described in: "Target prediction for indirect jumps" by Chang, Hao, and Patt http://dl.acm.org/citation.cfm?id=264209 This is a re-spin of fb9d142 after the revert (bd1c6789).
