Hi all,
This patch is about to enable binutils support for Key Locker,
Key Locker provides a mechanism to encrypt and decrypt data with an AES key without having access
to the raw key value by converting AES keys into "handles", more details please refer to
https://software.intel.com/content/www/us/en/develop/download/intel-key-locker-specification.html
Make check-gas is ok.
Enable support to Intel Key locker instructions.
