Paolo Bonzini 14cb949a3e target-i386: key sfence availability on CPUID_SSE, not CPUID_SSE2 ...

sfence was introduced before lfence and mfence.  This fixes Linux
2.4's measurement of checksumming speeds for the pIII_sse
algorithm:

md: linear personality registered as nr 1
md: raid0 personality registered as nr 2
md: raid1 personality registered as nr 3
md: raid5 personality registered as nr 4
