stats: Rename num_syscalls to numSyscalls in the reference stats.

The name of the stat was changed in the following change which broke all the
reference outputs.

stats: Get all stats updated to reflect current behaviour

Line everything up again.

stats: Update stats to reflect cache changes

stats: Update stats to reflect recent changes to floats

Mostly just splitting out the floats ops and corresponding
reads/writes.

stats: update references

stats: Update to match classic memory changes

stats: update references

stats: Add power stats to test references

stats: update and fix e273e86a873d

stats: update for snoop filter tweak

stats: Update stats to reflect cache changes

Removed unused stats, now counting WriteLineReq, and changed how
uncacheable writes are handled while responses are outstanding.

stats: Match current behaviour

Small changes to the branch predictor and BTB caused stats changes
throughout.

stats: Update stats to reflect changes to cache and crossbar

stats: Update stats to match cache changes

stats: Update stats to reflect snoop-filter changes

stats: updates due to recent changesets including d0934b57735a

stats: Update stats for cache, crossbar and DRAM changes

This update includes the changes to whole-line writes, the refinement
of Read to ReadClean and ReadShared, the introduction of CleanEvict
for snoop-filter tracking, and updates to the DRAM command scheduler
for bank-group-aware scheduling.

Needless to say, almost every regression is affected.

stats: Update MinorCPU regressions after accounting fix

stats: Update stats to reflect cache changes

stats: arm: updates

stats: update Minor stats due to PF bug fix

A recent changeset of mine (http://repo.gem5.org/gem5/rev/4cfe55719da5)
inadvertently fixed a bug in the Minor CPU model which caused it to treat
software prefetches as regular loads. Prior to this changeset, Minor
did an ad-hoc generation of memory commands that left out the PF check;
because it now uses the common code that the other CPU models use,
it generates prefetches properly. These stat changes reflect the fact
that the Minor model now issues SoftPFReqs.

stats: Update stats to reflect cache and interconnect changes

This is a bulk update of stats to match the changes to cache timing,
interconnect timing, and a few minor changes to the o3 CPU.

stats: changes due to recent changesets.

stats: Bump stats for decoder, TLB, prefetcher and DRAM changes

Changes due to speculative execution of an unaligned PC, introduction
of TLB stats, changes and re-work of the prefetcher, and the
introduction of rank-wise refresh in the DRAM controller.

stats: Bump stats for fixes, mostly TLB and WriteInvalidate

stats: Add DRAM power statistics to reference output

stats: Bump stats for filter, crossbar and config changes

This patch bumps the stats to reflect the addition of the snoop filter
and snoop stats, the change from bus to crossbar, and the updates to
the ARM regressions that are now using a different CPU and cache
configuration. Lastly, some minor changes are expected due to the
activation cleanup of the CPUs.

stats: Update stats for CPU and cache changes

This patch updates the stats to reflect the fixes and changes to the
CPU (mainly the o3), and the caches.

cpu: Minor CPU add regression tests for ARM and ALPHA

This patch adds regression tests results and test harnesses
for the Minor CPU on ARM and ALPHA.
