Re: [RFA/i386] Prec x86 MMX 3DNow! SSE SSE2 SSE3 SSSE3 SSE4 support

[Hui Zhu <teawater at gmail dot com>]

Hi Michael,

I make a new testsuite that can support sse and sse4 better.

When the pc doesn't support sse4 insn, the test will skip the sse4 insn test.

Please help me review it.

Thanks,
Hui
