Wrote a vif 'unpack' packet recompiler.
Compatibility is probably the same as the newVif interpreter code, but its faster. Speedwise its similar to the old-vif unpack code (the one currently enabled by default in pcsx2). Its about 0~2% slower on my machine from my limited testing, but I assume people with SSE4.1 cpus might have a lot better results since I added a lot of sse4.1 optimizations... The SSE4.1 optimizations were also ported to the newVif interpreter code. Also the "filling mode" should be fast compared to the old-vif unpack code since its sse optimized, but most games don't use this mode so it hasn't been tested much... git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2358 96395faa-99c1-11dd-bbfe-3dabce05a288
