llvmpipe: Update/correct CPU requirements.

Browse source 
There are no hard requirements at the moment.

We don't really emit any sse3 yet. Just some ssse3.

Thanks to Roland for spotting these incorrections.

@ -51,9 +51,13 @@ Requirements
- Linux
- A x86 or amd64 processor with support for sse2, sse3, and sse4.1 SIMD
instructions. This is necessary because we emit several SSE intrinsics for
convenience. See /proc/cpuinfo to know what your CPU supports.
- A x86 or amd64 processor. 64bit mode is preferred.
Support for sse2 is strongly encouraged. Support for ssse3, and sse4.1 will
yield the most efficient code. The less features the CPU has the more
likely is that you ran into underperforming, buggy, or incomplete code.
See /proc/cpuinfo to know what your CPU supports.
- LLVM 2.5 or greater. LLVM 2.6 is preferred.
