cpu: generate SimPoint basic block vector profiles
This patch is based on http://reviews.m5sim.org/r/1474/ originally written by Mitch Hayenga. Basic block vectors are generated (simpoint.bb.gz in simout folder) based on start and end addresses of basic blocks. Some comments to the original patch are addressed and hooks are added to create and resume from checkpoints based on instruction counts dictated by external SimPoint analysis tools. SimPoint creation/resuming options will be implemented as a separate patch.
