获得CPU的信息
/*
* 用汇编获得CPU信息
eax=0 调用cpuid
ebx,edx,ecx 返回cpu的oem信息
eax=0 调用cpuid
eax 的8--11位表明是几86
3--------386
4--------486
5--------Pentium
6--------Pentium pro Pentium II
2--------Dual Processors
检测是否是p6购架
eax=1 cpuid
如果al=1，是Pentium pro Pentium II
amd cpu
eax = 80000001 cpuid
---------------------
eax=51h AMD k5
eax =66h k6
