Stream out default optimization nodes
Hi, this patch makes us to store default optimization node same way as we stream target node. This means that command line options given at compile time prevail those given at linktime. Previously we sort of combined both. We still have a lot of flags that are global (i.e. not marked as Optimization) but affect way how the unit is output. Since I woul dlike to replace the old option merging, I would like to add Global attribute to each of them in .opt file and generate streaming code for them same way as we do for optimization/target nodes.
