* Reorganize the global value kinds. This: - renames "deref" global values to "load" and gives it a offset that works like the "load" instructions' does - adds an explicit "iadd_imm" global value kind, which replaces the builtin iadd in "vmctx" and "deref" global values. - also renames "globalsym" to "symbol"
