Log Message:
-----------
Entire backup algorithm now completes normally for all marc's exceptionhandler test code.  Now need to generated the specifications to make sure all related formal semantics are correct.  Also cleanup of 2D graphics display in progress

Fixed athrow creator bug.  Each exception thrown by an instruction is supposed to have its own athrow creator to figure out how to route the exception to the various handlers supplied in the code block of the method.  All such athrow creator instructions have to be available to the scanner for scheduling in the branch choice generator, so that they are properly scanned.  At a different execution point, the handlers need to be available to the buildFormalPeer method of the throwing instruction, so that the proper formal semantics can be wired in.

The brain-dead bug was that all exceptions for an instruction were being routed through the same athrow creator.  Even though the athrow creators were being stockpiled in advance, they were not being used.  To fix this problem, the creation of athrow creators is now the responsibility of the individual instruction classes. An instruction which throws now implements the ThrowsException interface. The creators are created during the initialization of the instruction.  The new design binds an athrow creator to the Exception class it represents in much more sane, type safe way.

NOTE: The flag "mustPop2" appears to be obsolete in the C++ code, and so has been dropped in MangoJPF.  The original comment for this flag was "Also, if the parameter mustPop2 is TRUE, then this athrowcreator follows an invocation, and must pop the extra frame."    

Historical note:  The original C++ had a one-size-fits-all instruction class, so no sane design for the athrow creators was possible in that world.
