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.

Include methods that allow a memory operation to be split between the part that initiates the access, and the part that completes the access. In these functions the Mem variable is explicitly declared; in the default execute functions, the Mem variable is still handled through %(op_decl)s.
arch/isa_parser.py:
Include recording the type of the memory access variable so that it can be used if it needs to be explicitly declared in a template.
Have memory operands consider themselves neither a source nor a destination to avoid including themselves on the op_src_decl list or the op_dest_decl list.
Record op_src_decl and op_dest_decl lists to allow for declaring only source or destination operands. This is needed for the split memory access methods.
