Subject: integrating recent changes from fermi-test into fermi (i'll use
 "fermi" for more disruptive changes to the pipeline model such as updating
 the MSHRs and getting rid of the warp tracker, ripping out DWF, etc...)

[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 7805]
