perf/tests: Add AVX512-FP16 instructions to x86 instruction decoder test

Browse source 
The x86 instruction decoder is used for both kernel instructions and
user space instructions (e.g. uprobes, perf tools Intel PT), so it is
good to update it with new instructions.

Add AVX512-FP16 instructions to x86 instruction decoder test.

A subsequent patch adds the instructions to the instruction decoder.

Intel AVX512-FP16 Architecture Specification

Example:

  $ perf test -v "x86 instruction decoder" |& grep vfcmaddcph | head -2
  Failed to decode: 62 f6 6f 48 56 cb     vfcmaddcph %zmm3,%zmm2,%zmm1
  Failed to decode: 62 f6 6f 48 56 8c c8 78 56 34 12      vfcmaddcph 0x12345678(%eax,%ecx,8),%zmm2,%zmm1
