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.

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.
