Subject: [PATCH] SSE2/64-bit: Fix trans. segfault w/ malformed JPEG

Attempting to losslessly transform certain malformed JPEG images can
cause the nbits table index in the Huffman encoder to exceed 32768, so
we need to pad the SSE2 implementation of that table to 65536 entries as
we do with the C implementation.

Regression introduced by 087c29e07f7533ec82fd7eb1dafc84c29e7870ec

Fixes #543
