f066bfc2f5 cpu: get rid of uncached access "events" 
These recordEvent() calls could cause crashes since they
access the req pointer after it's potentially been
deleted during a failed translation call.  (Similar
problem to the traceData bug fixed in the previous cset.)

Moving them above the translation call (as was done
recentlyi in cset 8b2b8e5e7d35) avoids the crash
but doesn't work, since at that point we don't know if
the access is uncached or not.

It's not clear why these calls are there, and no one
seems to use them, so we'll just delete them.  If they
are needed, they should be moved to somewhere that's
guaranteed to be after the translation completes but
before the request is possibly deleted, e.g., in
finishTranslation().

4d77ea7a57 cpu: fix exec tracing memory corruption bug 
Accessing traceData (to call setAddress() and/or setData())
after initiating a timing translation was causing crashes,
since a failed translation could delete the traceData
object before returning.

It turns out that there was never a need to access traceData
after initiating the translation, as the traced data was
always available earlier; this ordering was merely
historical.  Furthermore, traceData->setAddress() and
traceData->setData() were being called both from the CPU
model and the ISA definition, often redundantly.

This patch standardizes all setAddress and setData calls
for memory instructions to be in the CPU models and not
in the ISA definition.  It also moves those calls above
the translation calls to eliminate the crashes.

f9408f984f ruby: Changed the default set size to 1 
Previously, the set size was set to 4.  This was mostly do to the fact that a
crazy graduate student use to create networks with 256 l2 cache banks.  Now it
is far more likely that users will create systems with less than 64 of any
particular controller type.  Therefore Ruby should be optimized for a set size
of 1.

possible.
