It's probably time for doing this. The included methods are a nice way to
show the concept of Smalltalk methods being translated to C for efficiency,
but they are rather inconvenient with regard to version control.

In addition to MiscPrimitivePlugin, we also have SoundGeneratorPlugin and
ADPCMCodecPlugin that use included methods. IncludedMethodsTest in VMMaker
is my attempt to keep track of these.

I presume that the sensible thing to do would be to just copy the necessary
methods directly into the plugins under different names and generate them
directly as with any other primitive. As Sista makes the primitives redundant,
just stop calling them.
