------- Additional Comments from Judit Jász <jasy at inf.u-szeged.hu>
I have modified my earlier patch. 
My aim with the refactoring of the CodeGenerator is to see how the implemented
peepholes work now. Because they use the same steps almost everywhere, the code
could be more understandable if we can reduce the number of duplicated code
fragments. 

An other aim of this work is to eliminating the unnecessary steps of these
peepholes. In these peepholes we change only the opcode of the last
instructions and some of the operands. It is unnecessary to delete the last
instruction and build a new one, it is suffucuent if we change the
corresponding part of the last instruction.
