That doesn't entail changes in tooling, but silences this perf build

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.

Add support for decoding instructions for Intel Processor Trace. The
kernel x86 instruction decoder is copied for this.
This essentially provides intel_pt_get_insn() which takes a binary
buffer, uses the kernel's x86 instruction decoder to get details of the
instruction and then categorizes it for consumption by an Intel PT
decoder.
