x86: Add AMD prefetch and 3DNow! opcodes to opcode map
Add AMD prefetch and 3DNow! opcode including FEMMS. Since 3DNow!
uses the last immediate byte as an opcode extension byte, x86
insn just treats the extenstion byte as an immediate byte
instead of a part of opcode (insn_get_opcode() decodes first
"0x0f 0x0f" bytes.)
Users who are interested in analyzing 3DNow! opcode still can
decode it by analyzing the immediate byte.
