x86/insn: perf tools: Add new memory instructions

Intel Architecture Instruction Set Extensions Programing Reference (Oct
2014) describes 3 new memory instructions, namely clflushopt, clwb and
pcommit. Add them to the op code map and the perf tools new
instructions test. e.g.

$ tools/perf/perf test "x86 ins"
39: Test x86 instruction decoder - new instructions : Ok

Or to see the details:

$ tools/perf/perf test -v "x86 ins"
