24fb0f88ed Add optimized x86-64 implementation of strnlen. 
While at it, beef up the test suite for strnlen and add performance
tests for it, too.

8e96b93aa7 Speed up x86-64 strcasestr a bit moew. 
Using the new SSE4.2 instructions is cool but not really the fastest.
Some older SSE instructions can do the trick faster.

6fb8cbcb58 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.
