mips-tlb-fix: check for alignment faults.\nMIPS was never updated to use TLBS correcty in SE mode. The error was forwarding translations directly to pageTable. The TLB should check for alignment faults at bare minimum here but in the long run we should be using TLBs in SE mode for MIPS.

o3, inorder: fix FS bug due to initializing ThreadState to Halted.
...
For some reason o3 FS init() only called initCPU if the thread state
was Suspended, which was no longer the case. There's no apparent
reason to check, so I whacked the test completely rather than
changing the check to Halted.
The inorder init() was also updated to be symmetric, though the
previous code was just a fancy no-op.

o3: handle fetch with no active threads correctly.
...
This situation can arise now on the first fetch cycle after
the last active thread is halted. It seems easy enough to
deal with when it happens rather than trying to avoid it.

ThreadState: initialize status to Halted in constructor.
...
This provides a common initial status for all threads independent
of CPU model (unlike the prior situation where CPUs initialized
threads to inconsistent states).
This mostly matters for SE mode; in FS mode, ISA-specific startupCPU()
methods generally handle boot-time initialization of thread contexts
(since the right thing to do is ISA-dependent).

Get rid of the Unallocated thread context state.
...
Basically merge it in with Halted.
Also had to get rid of a few other functions that
called ThreadContext::deallocate(), including:
- InOrderCPU's setThreadRescheduleCondition.
- ThreadContext::exit(). This function was there to avoid terminating
simulation when one thread out of a multi-thread workload exits, but we
need to find a better (non-cpu-centric) way.
