x86/insn: perf tools: Add new SHA instructions

Intel SHA Extensions are explained in the Intel Architecture
Instruction Set Extensions Programing Reference (Oct 2014).
There are 7 new instructions.  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" 2>&1 | grep sha

Committer note:

3 lines of details, for the curious:

  $ perf test -v "x86 ins" 2>&1 | grep sha256msg1 | tail -3
  Decoded ok: 0f 38 cc 84 08 78 56 34 12 	sha256msg1 0x12345678(%rax,%rcx,1),%xmm0
  Decoded ok: 0f 38 cc 84 c8 78 56 34 12 	sha256msg1 0x12345678(%rax,%rcx,8),%xmm0
  Decoded ok: 44 0f 38 cc bc c8 78 56 34 12 	sha256msg1 0x12345678(%rax,%rcx,8),%xmm15
