x86: change representation of extension opcode

Browse Source 
Having a "None" field in the vast majority of entries is needlessly
cluttering the overall table. Instead of this being a separate field,
use a representation matching that of Intel SDM and AMD PM for the main
use of the field: Append the value after a / as the separator.
