The major change is renaming the old ExecContext to CPUExecContext, and creating two new classes, ExecContext (an abstract class), and ProxyExecContext (a templated class that derives from ExecContext).
Code outside of the CPU continues to use ExecContext as normal (other than not being able to access variables within the XC). The CPU uses the CPUExecContext, or however else it stores its own state. It then creates a ProxyExecContext, templated on the class used to hold its state. This proxy is passed to any code outside of the CPU that needs to access the XC. This allows code outside of the CPU to use the ExecContext interface to access any state needed, without knowledge of how that state is laid out.
Note that these changes will not compile without the accompanying revision to automatically rename the shadow registers.

For now, we must get the boot cpu's frequency as a parameter

single place so it's easier to work with.
- Add support for binning kernel/user/idle time separately from
lisa's binning stuff, but make the two compatible.
- KernelStats used to directly implement the pImpl idiom, but
it makes more sense to just remove the level of indirection and
make the exec context have a pointer to the stats.
- Factor common code out of LinuxSystem and Tru64System and put
it into the System base class. While doing that, make all
constructors take a pointer to a parameter struct instead of
naming the parameters individually to make it much easier to add
parameters to these classes.
SConscript:
Move the function tracking and binning stuff around.

kernelStats no longer has the level of indirection in it,
execContext has the indirection now. so, kernelStats is a pointer.
We also need a pointer to the kernelBinning stuff from the system

Move a whole bunch of code into kern_binning.cc so it's all
in the same place.
cpu/exec_context.hh:
We want pointers to the kernel binning/stats stuff and we'll

Also various changes to make the CPU model less ISA dependent, which includes moving the code that checks for interrupts up to the ISA level, moving code that zeroes the zero registers up to the ISA level, and removing opcode and ra from the regfile.
arch/alpha/alpha_memory.cc:
The regfile has been changed so it no longer has the opcode and ra. Instead the xc holds the actual instruction, and from there the opcode and ra can be obtained with OPCODE() and RA().
arch/alpha/ev5.cc:
Moved code that once existed within simpleCPU to ev5, and templatized it.
This way the CPU models can call processInterrupts and the ISA specific interrupt handling is left to the ISA's code.
Also moved ISA specific zero registers from simpleCPU to here.
arch/alpha/ev5.hh:
Added macros for obtaining the opcode and ra from the instruction itself, as there is no longer opcode or ra in the regfile.
arch/alpha/isa_desc:
Added in declarations for the FastCPU model.
arch/alpha/isa_traits.hh:
Removed opcode and ra from the regfile. The xc now holds the actual instruction, and the opcode and ra can be obtained through it.
Also added the declaration for the templated zeroRegisters() function, which will set the zero registers to 0.
arch/isa_parser.py:
Added in FastCPUExecContext so it will generate code for the FastCPU model as well.
cpu/exec_context.cc:
Added in a more generic trap function so "ev5_trap" doesn't need to be called. It currently still calls the old method, with plans for making this ISA dependent in the future.
cpu/exec_context.hh:
Exec context now has the instruction within it. Also added methods for exec context to read an instruction from memory, return the current instruction, and set the instruction if needed.
Also has declaration for more generic trap() function.
cpu/simple_cpu/simple_cpu.cc:
Removed references to opcode and ra, and instead sets the xc's instruction with the fetched instruction.
