Correct CpuMax in i386-opc.h
CpuMax should be CpuIntel64, not CpuNo64. i386-gen.c is updated to
verify that CpuMax is correct. X86 assembler is updated to properly
set cpuamd64 and cpuintel64.

PR gas/20154
* config/tc-i386.c (intel64): New.
(cpu_flags_match): Set cpuamd64 and cpuintel64.
(md_parse_option): Set intel64 instead of cpuamd64 and
cpuintel64.

PR gas/20154
* i386-gen.c (main): Fail if CpuMax is incorrect.
* i386-opc.h (CpuMax): Set to CpuIntel64.
* i386-tbl.h: Regenerated.
