stats: update references

stats: Update to match ARM ISA changes

stats: update stats for mmap() change.

SE O3 runs see an additional reg read per mmap() call.

stats: update for previous changeset

Very small differences in IQ-specific O3 stats.

stats: update stats for cache occupancy and clock domain changes

tests: update reference outputs

Apparently only stats.txt was updated the last time, so
this changeset updates other reference output files
(config.ini, simout, simerr, ruby.stats) so that
test output diffs should not be cluttered with irrelevant
changes. There are a few stats.txt updates too, but
they are in the minority.

regressions: update due to cache latency fix

stats: update stats for previous changes.

update stats for preceeding changes

Stats: Updates due to bus changes

This patch bumps all the stats to reflect the bus changes, i.e. the
introduction of the state variable, the division into a request and
response layer, and the new default bus width of 8 bytes.

Stats: Update stats for RAS and LRU fixes.

ARM: Update stats for CBNZ fix.

SE/FS: Make both SE and FS tests available all the time.
