Find Ways to Reduce Executable Size

PySide's code generator does a good job in automatically creating wrappers and support functions for everything. The problem with that is that it creates lots of similar code.

By identifying repeated patterns, it should be possible to build more general functions, which are called with the same arity but different parameter values.

The first step before creating actual different code is to prepare some measurement how much the generated functions can be folded. This should give some factor to be the expected saving.
