Add support for CPUID PREFETCHWT1
Latest AVX512 spec
http://download-software.intel.com/sites/default/files/managed/50/1a/319433-018.pdf
Has CPUID PREFETCHWT1 for prefetchwt1 instruction, which we list as AVX512PF.
This patch introduces CPUID PREFETCHWT1.
gas/
* config/tc-i386.c (cpu_arch): Add .prefetchwt1.
* doc/c-i386.texi: Document .prefetchwt1/prefetchwt1.
opcodes/
* i386-gen.c (cpu_flag_init): Add CPU_PREFETCHWT1_FLAGS/
(cpu_flags): Add CpuPREFETCHWT1.
* i386-init.h: Regenerate.
* i386-opc.h (CpuPREFETCHWT1): New.
(i386_cpu_flags): Add cpuprefetchwt1.
* i386-opc.tbl: Cahnge CPU of prefetchwt1 from CpuAVX512PF to CpuPREFETCHWT1.
* i386-tbl.h: Regenerate.
