cpu: implement an L-TAGE branch predictor
This patch implements an L-TAGE predictor, based on André Seznec's code available from
CBP-2 (http://hpca23.cse.tamu.edu/taco/camino/cbp2/cbp-src/realistic-seznec.h). The
patch also changes the default branch predictor of o3 from the tournament predictor
to L-TAGE.This patch requires patch #3727 (http://reviews.gem5.org/r/3727/) to compile.
