[PATCH] Optimize strstr, strcasestr and memmem

[Joseph S. Myers]

Anyone interested in performance of these functions may also be interested 
in bug 12100, where the SSE4 version of strstr reintroduces the unwanted 
quadratic asymptotic performance.  (This is not a comment on your patch 
itself, but a mention of something people looking at this area might also 
be interested in.)
