Fortunately the toolchain is open source and the changes for ARMv8 can be viewed publicly, for instance here:

http://sourceware.org/git/?p=binutils.git;a=tree;f=opcodes;h=4d2802e56168233beb536e928540bab4f8597914;hb=de9b7f70041576cc9982495aacd65bd8d4a7b2eb

Check out the files starting with aarch64. Also, this file:

http://sourceware.org/git/?p=binutils.git;a=blob_plain;f=include/opcode/aarch64.h;hb=de9b7f70041576cc9982495aacd65bd8d4a7b2eb
