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).
