x86/insn: Add Key Locker instructions to the opcode map

Browse source 
The x86 instruction decoder needs to know these new instructions that
are going to be used in the crypto library as well as the x86 core
code. Add the following:

LOADIWKEY:
	Load a CPU-internal wrapping key.

ENCODEKEY128:
	Wrap a 128-bit AES key to a key handle.

ENCODEKEY256:
	Wrap a 256-bit AES key to a key handle.

AESENC128KL:
	Encrypt a 128-bit block of data using a 128-bit AES key
	indicated by a key handle.

AESENC256KL:
	Encrypt a 128-bit block of data using a 256-bit AES key
	indicated by a key handle.

AESDEC128KL:
	Decrypt a 128-bit block of data using a 128-bit AES key
	indicated by a key handle.

AESDEC256KL:
	Decrypt a 128-bit block of data using a 256-bit AES key
	indicated by a key handle.

AESENCWIDE128KL:
	Encrypt 8 128-bit blocks of data using a 128-bit AES key
	indicated by a key handle.

AESENCWIDE256KL:
	Encrypt 8 128-bit blocks of data using a 256-bit AES key
	indicated by a key handle.

AESDECWIDE128KL:
	Decrypt 8 128-bit blocks of data using a 128-bit AES key
	indicated by a key handle.

AESDECWIDE256KL:
	Decrypt 8 128-bit blocks of data using a 256-bit AES key
	indicated by a key handle.

The detail can be found in Intel Software Developer Manual.
