perf tools: Add AVX-512 support to the instruction decoder used by Intel PT
Add support for Intel's AVX-512 instructions to perf tools instruction
decoder used by Intel PT. The kernel's instruction decoder was updated in
a previous patch.
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.
A representative set of instructions is added to the perf tools new
instructions test in a subsequent patch.
