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.

stats: update references

stats: update stats for ld.so support

Additional auxv entries leads to more instructions in start-up
while walking the list, along with different cache conflicts
wrt stack entries.

stats: update stats for mmap changes

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: 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.

x86 regressions: stats update due to new x87 instructions

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.

Stats: Update stats for RAS and LRU fixes.

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.

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

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