stats: Update some stats after simulated program exit behavior was changed.

The following CL delayed program exit and changed the stats for many if not
most of the SE mode regressions.

tests: Regression stats updated for recent patches

stats: update references

stats: update references

stats: update stats for mmap() change.

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

stats: update stats to after GPU checkin

stats: bump stats to reflect ruby tester changes

stats: updates due to recent chagnesets

stats: update for previous changeset

Very small differences in IQ-specific O3 stats.

stats: update for O3 changes

Mostly small differences in total ticks, but O3 stall causes
shifted significantly.

30.eon does speed up by ~6% on Alpha and ARM, and 50.vortex
by 4.5% on ARM. At the other extreme, X86 70.twolf is 0.8%
slower.

stats: update stats for cache occupancy and clock domain changes

test: update stats

Update stats for recent changes. Mostly minor changes
in register access stats due to addition of new cc
register type and slightly different (and more accurate)
classification of int vs. fp register accesses.

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

regressions: x86: stats updates due to new x87 insts

regressions: update stats due to branch predictor changes
The actual statistical values are being updated for only two tests belonging
to sparc architecture and inorder cpu: 00.hello and 02.insttest. For others
the patch updates config.ini and name changes to statistical variables.

stats: update stats for previous changes.

x86 regressions: stats update due to new x87 instructions

update stats for preceeding changes

x86 Regressions: Update stats due to register predication

stats: Update stats for syscall emulation Linux kernel 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.

all: Update stats for memory per master and total fix.

X86: Update stats for the CPUID change.

X86 Regression: update stats due to cc register split

stats: update stats for no_value -> nan
Lots of accumulated older changes too.

bp: fix up stats for changes to branch predictor

stats: update stats for insts/ops and master id changes

Yet another merge with the main repository.

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