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.
