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.
Re-use the existing traffic generator regression, and enable the stack
distance calculation in the comm monitor, along with the verification
stack.
The traffic generator config is also tuned to not increase the
run-time too much (and actually have some address re-use).
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.
This patch avoids building the 'inorder' CPU model for any permutation
of ALPHA, and also removes the ALPHA regressions using the 'inorder'
CPU. The 'minor' CPU is already providing a broader test coverage.
Only printing one rather than two args for the ignored syscall
warning means the count of register accesses has changed on
a few runs. Oddly only Alpha Tru64 seems to have any ignored
syscalls in the regression tests.
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.
This patch reflects the recent name change in the DRAM TrafficGen
tests and also tidies up the test directory.

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.
The updates to the x87 caused the stats for several regressions to
change. This was mainly caused by the addition of a working 32-bit and
80-bit FP load instruction and xsave support.
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.
This patch simply takes a first step to use the NULL ISA build for
tests that do not make use of a CPU. Most of the Ruby tests could go
the same way, but to avoid duplicating a lot of compilation targets
that will have to wait until Ruby is built as a library and linked in
independently.
