This diff suppresses the output of C++ for the "pure" classes defined in system/classes, and it rips out all the uses of MethodCallPackage (except for the i_* and ifa_* helpers, which we can go after separately). Also cleans up a bunch of "if (hhvm)" and "#ifdef HHVM" checks in builtin_functions.cpp, systemlib.cpp, object_data.cpp, and class_info.cpp (and the corresponding .h files). Note that this does not completely remove the generated C++ files. We still generate code for the PHP files in "system/globals" and we still generate the g_class_map (because the VM needs g_class_map at startup when it creates Class's for the extensions). We also still have the dynamic_func_table/dynamic_class_table stuff, MethodCallPackage, and the i_* and ifa_* helpers to support invoke_builtin() (which is still used by the compiler).
