    Add support for Intel's AVX-512 instructions to the instruction decoder.
    
    AVX-512 instructions are documented in Intel Architecture Instruction
    Set Extensions Programming Reference (February 2016).
    
    AVX-512 instructions are identified by a EVEX prefix which, for the
    purpose of instruction decoding, can be treated as though it were a
    4-byte VEX prefix.
    
    Existing instructions which can now accept an EVEX prefix need not be
    further annotated in the op code map (x86-opcode-map.txt). In the case
    of new instructions, the op code map is updated accordingly.
    
    Also add associated Mask Instructions that are used to manipulate mask
    registers used in AVX-512 instructions.
    
    The 'perf tools' instruction decoder is updated in a subsequent patch.
    And a representative set of instructions is added to the perf tools new
    instructions test in a subsequent patch.
