17dbb49294 tests: Update SMT tests to correctly configure CPUs
The 01.hello-2T-smt test case for the O3 CPU didn't correctly setup
the number of threads before creating interrupt controllers, which
confused the constructor in BaseCPU. This changeset adds SMT support
to the test configuration infrastructure.

582a0148b4 config,cpu: Add SMT support to Atomic and Timing CPUs
Adds SMT support to the "simple" CPU models so that they can be
used with other SMT-supported CPUs. Example usage: this enables
the TimingSimpleCPU to be used to warmup caches before swapping to
detailed mode with the in-order or out-of-order based CPU models.

a3f49f60c7 mem: Move trace functionality from the CommMonitor to a probe
This changeset moves the access trace functionality from the
CommMonitor into a separate probe. The probe can be hooked up to any
component that exports probe points of the type ProbePoints::Packet.

This patch moves the dependency on Google's Protocol Buffers library
from the CommMonitor to the MemTraceProbe, which means that the
CommMonitor (including stack distance profiling) no long depends on
it.

a0cbf55411 stats: Update pc-switcheroo stats
The pc-switcheroo test cases has slightly different timing after
decoupling draining from the SimObject hierarchy. This is expected
since objects aren't drained in the exact same order as before.

f16c0a4a90 sim: Decouple draining from the SimObject hierarchy
Draining is currently done by traversing the SimObject graph and
calling drain()/drainResume() on the SimObjects. This is not ideal
when non-SimObjects (e.g., ports) need draining since this means that
SimObjects owning those objects need to be aware of this.

This changeset moves the responsibility for finding objects that need
draining from SimObjects and the Python-side of the simulator to the
DrainManager. The DrainManager now maintains a set of all objects that
need draining. To reduce the overhead in classes owning non-SimObjects
that need draining, objects inheriting from Drainable now
automatically register with the DrainManager. If such an object is
destroyed, it is automatically unregistered. This means that drain()
and drainResume() should never be called directly on a Drainable
object.

While implementing the new functionality, the DrainManager has now
been made thread safe. In practice, this means that it takes a lock
whenever it manipulates the set of Drainable objects since SimObjects
in different threads may create Drainable objects
dynamically. Similarly, the drain counter is now an atomic_uint, which
ensures that it is manipulated correctly when objects signal that they
are done draining.

A nice side effect of these changes is that it makes the drain state
changes stricter, which the simulation scripts can exploit to avoid
redundant drains.

This update includes the changes to whole-line writes, the refinement
of Read to ReadClean and ReadShared, the introduction of CleanEvict
for snoop-filter tracking, and updates to the DRAM command scheduler
for bank-group-aware scheduling.

Needless to say, almost every regression is affected.

893533a126 mem: Allow read-only caches and check compliance
This patch adds a parameter to the BaseCache to enable a read-only
cache, for example for the instruction cache, or table-walker cache
(not for x86). A number of checks are put in place in the code to
ensure a read-only cache does not end up with dirty data.

A follow-on patch adds suitable read requests to allow a read-only
cache to explicitly ask for clean data.

172385ae9f stats: x86: changes due to recent patches
The change in 20.parser is from new x87 instructions.  The change to
pc-o3-timing is not clear to me.  It seems that this test might be invoking
some undefined behavior.
