x86/insn: perf tools: Add new xsave instructions
Add xsavec, xsaves and xrstors to the op code map and the perf tools new
instructions test. To run the test:
$ 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" 2>&1 | grep 'xsave\|xrst'
For information about xsavec, xsaves and xrstors, refer the Intel SDM.
