SSSE3 strcpy/stpcpy for x86-64
...
This patch adds SSSE3 strcpy/stpcpy. I got up to 4X speed up on Core 2
and Core i7. I disabled it on Atom since SSSE3 version is slower for
shorter (<64byte) data.

Optimize x86-64 strlen for SSE4.2.
...
The SSE4.2 implementation is used in the DSO only. The patch also adds
some infrastructure to be used in similar code later one.
