( -- addr )
Pushes the address of the kernel-allocated exception vector table to the stack. This is allocated in the kernel so it is guaranteed to have proper alignment, since it needs a rather large one. (In the future, this might change, and it may instead be allocated inside a frame allocated by the standard frame allocator.)
