x86, insn: Add new opcodes as of June, 2013

Add TSX-NI related instructions and new instructions to x86-opcode-map.txt according to the Intel(R) 64 and IA-32 Architectures Software Developer's Manual Vol2C (June, 2013). This also includes below updates. - Fix a typo of MWAIT (the lack of (11B)). - Change NOP Ev to prefetchw Ev - Add CRC32 new prefix style (66&F2) - Add ADCX, ADOX, RDSEED, CLAC and STAC instructions Signed-off-by: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Link: http://lkml.kernel.org/r/20130806073750.4049.12365.stgit@udc4-manage.rcp.hitachi.co.jp Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Ingo Molnar <mingo@redhat.com> Cc: "H.
