stats: update references

stats: Update for UDelayEvent quiesce change

stats: Update ARM stats to include programmable oscillators

stats: update a few stats from long O3 runs

Very small changes to iew.predictedNotTakenIncorrect
and iew.branchMispredicts. Looks like similar updates
were committed on April 3 (changeset 235ff1c046df), but
only for the quick tests.

tests: Update regressions for the new kernels and various preceeding fixes.

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.

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.

arm regressions: updates to config.ini, terminal files

ARM: update stats for clock frequency fix.

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

ARM: Update stats for valgrind fix and replace config.inis which are out of date.

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