I thought __attribute__((aligned)) did that (there also seems to be a
__BIGGEST_ALIGNMENT__ macro?). However, I'm not sure if it's wise to use that
in a library header, since it may change depending on the compiler command line
options AIUI. Maybe a specific alignment that's known to be good enough on all
supported platforms will do (synced to whatever GSlice does). But in any case,
adding it to GType and GTypeClass fixes most issues with type instance and
class cast.

However, there are still other issues, esp. with GArray's g_array_free(FALSE)
etc.
