Create a new Serialization module that contains all the PCH code, and will contain all the module code in the future. Update the Makefiles, CMake projects and the Xcode project. I hope I did everything right for Xcode. No functionality change.

Move the decision logic whether it's a good idea to split a critical edge to clients. Also fixed an erroneous check. An edge is only a back edge when the from and to blocks are in the same loop.

its trivial PHI nodes, since it's easy.

Add an option to disable codegen prepare critical edge splitting. In theory, PHI elimination is already doing all (most?) of the splitting needed. But machine-licm and machine-sink seem to miss some important optimizations when splitting is disabled.
