[SPARC64]: Make IVEC pointers 64-bit.
Currently we chain IVEC entries using 32-bit "pointers" because we know that the ivector_table is in the main kernel image, thus below 4GB. This uses proper 64-bit pointers instead. Whilst this bloats up the kernel image size, this sets the infrastructure necessary to significantly shrink the kernel size by using physical addresses and dynamically allocating the ivector table.
