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.

Faster memcpy on x64. We add new memcpy version that uses unaligned loads which are fast on modern processors. This allows second improvement which is avoiding computed jump which is relatively expensive operation. Tests available here: http://kam.mff.cuni.cz/~ondra/memcpy_profile_result27_04_13.tar.bz2

Improve 64bit memcpy/memmove for Atom, Core 2 and Core i7 This patch includes optimized 64bit memcpy/memmove for Atom, Core 2 and Core i7. It improves memcpy by up to 3X on Atom, up to 4X on Core 2 and up to 1X on Core i7. It also improves memmove by up to 3X on Atom, up to 4X on Core 2 and up to 2X on Core i7.
