intel/ir: Uncomment definition of several unused hardware opcodes.

There are a number of opcode_desc table entries for many of these
unused opcodes.  A symbolic opcode enum will be required in a future
commit in order to keep them in the opcode description tables.  The
alternative would be to remove the unused opcodes from the opcode
description tables.
