Ondřej Bílka 584b18eb4d Add strstr with unaligned loads. Fixes bug 12100.
A sse42 version of strstr used pcmpistr instruction which is quite
ineffective. A faster way is look for pairs of characters which is uses
sse2, is faster than pcmpistr and for real strings a pairs we look for
are relatively rare.

For linear time complexity we use buy or rent technique which switches
to two-way algorithm when superlinear behaviour is detected.
