Look up the global constructor list that the linker outputs, and run them all. Required creation of the `kutil::no_construct` template for objects that are constructed before the global constructors are run. Also split the `memory_initialize` function into two - one for just those objects that need to happen before the global ctors, and one after. Tags: memory c++
