b47737dde7 Make sure all parameters have default values if they're 
supposed to and make sure parameters have the right type.
Also make sure that any object that should be an intermediate
type has the right options set.

ea70e6d6da Make branches work by repopulating the predecoder every time through. This is probably fine as far as the predecoder goes, but the simple cpu might want to not refetch something it already has. That reintroduces the self modifying code problem though.

6e286cddfa Get rid of the immediate and displacement components of the EmulEnv struct and use them directly out of the instruction. The extra copies are conceptually realistic but are just innefficient as implemented. Also don't use the zeroeth microcode register for general storage since it's now the zero register, and implement a load and a store microops.

- factor out checkFunctional() code so it can be
called from derived classes
- use EventWrapper for sendEvent, move event handling
code from event to port where it belongs
- make sendEvent a pointer so derived classes can
override it
- replace std::pair with new class for readability
