Final code

With the new C sources, my compiler could pass all the expected tests on C files. I could not find all the C++ libraries, so, it is not compiling all the .cpp files. But the new table is much better than the old one. The final code is here. I still plan to carry on many optimizations on this code, but I think the post-deconstruction of phi-functions will not add any benefits to the register allocator. What should be done is a graph based algorithm that uses maximum cardinality search to find a good coloring. This is my next step, and my project for this September.
