/// - Added new opcode PFNACC
/// - decreased number of opcodes (as it was suggested by k7 manual)
/// (using memory reference as operand of instructions)
/// - added PREFETCHW opcode. It has different semantic than k6-2
/// and saves 15-25 cpu clocks for athlon.
/// - partial unrolling loops for removing slower MOVW insns.
/// (Note probably same operation should be done for decode_3dnow)
/// - change function name for support 3DNowEx! automatic detect
///
/// note: because K7 processors are an aggresive out-of-order three-way
