bec41479af cpu-kvm: Reinitialize threads on drainResume 
Event queue service threads may have been re-created while the
simulator was drained. We therefore need to initialize the new thread
by setting correct signal masks and re-attaching performance counters.

8c685469f1 sim: Fix fork for multithreaded simulations 
It is currently not possible to call m5.fork when the simulator is
running in with multiple parallel event queues. The POSIX standard
have very weak guarantees when forking a process with multiple
threads. In order to use fork correctly, we need to ensure that all
helper threads servicing event queues have terminated before the fork
system call is invoked.

There are two ways this could be implemented: 1) Always terminate
helper threads when taking a global simulator exit event, or 2)
terminate helper threads just before fork is called from Python.

This change implements the second strategy since the KVM-based CPUs
currently assume that TIDs don't change unless there is a fork event.

53238f891d arch: Ensure using namespace * doesn't leak from generated ISA files. 
Only use "using namespace" with the *ISAInst namespace, not the top
level namespace. Also only using namespace *ISA, and not the gem5
namespace itself. The *ISAInst namespace is already in the gem5
namespace, and so will resolve names in it automatically.

fac84c1fe5 cpu-minor: Fix for minor CPU scoreboard 
When the scoreboard checks RAW dependency, it determines whether
the source registers can be forwarded or not to evaluate
relative latency. To do that, fuIndices[index] should be used
as an index for accessing cant_forward_from_fu_indices, not register
index itself. Moreover, since fuIndices[index] is cleared as -1
by clearInstDests(), the first compare should be fuIndices[index] != -1
instead of 1.

This part of the fix for the following nightly build error:
https://www.mail-archive.com/gem5-dev@gem5.org/msg40426.html.

The new resource downloader outputs messages to stdout informing the
user of the download status. For tests which compare the stdout to some
reference, these lines need ignored.

2c457d2a9f cpu: Fix TME for dyn_o3_cpu 
Commit c417b76 changed the behaviour of addRequest(),
but did not update documentation or the HTM-related logic that used it.

Updates documentation for addRequest() in light of c417b76,
refactors request class to be idiomatic and use assigned byteEnable,
made HTM cmds pass in a correct byteEnable.

e20e3cf47e scons: Change how the test object file suffix is applied. 
This had been done by prepending the letter "t" to the suffix, with the
intention of turning a suffix like ".o" to ".to". Unfortunately SCons
stores both the actual suffix and the "." in that variable, so what we
ended up with was ".o" => "t.o", so test.o would become testt.o.

This change updates that logic to prepend a ".t" in front of the
existing suffix, skipping over it's first character which is assumed to
be a ".".

The nightly tests were failing as reported here:

This was due to the tests trying to run our MI_Example test against
GCN3_X86 instead of the X86 ISA target. This patch fixes the issue.

Use templates to delegate knowing what these types are to whatever is using
InstResult. This will need to be even more generalized at these call
sights so that we don't just push around the dependencies, but that will
have to be handled later.
