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.

a faulting instruction is the fault handler, which appears as an independent
instruction to the timing model. New code will stall fetch and not fetch the
fault handler as long as there's a faulting instruction in the pipeline (i.e.,
the faulting inst has to commit first).
Also fix Ali's bad-address assertion that doesn't apply to full system.
Added some more debugging support in the process. Hopefully we'll move to the new
cpu model soon and we won't need it anymore.
arch/alpha/alpha_memory.cc:
Reorganize lookup() so we can trace the result of the lookup as well.

Replace "Dispatch" flag with "Pipeline" (since I added similar
DPRINTFs in other pipe stages).

Change default for printing mis-speculated instructions to true (since
that's often what we want, and right now you can't change it from the
