Comparing speedup and perfomance for strings with different lengthes.

Speedup through round up to fundamental types:
 - round up to 4 from: 3(in 9.3 times)
 - round up to 8 from: 5(5.8X), 6(5X), 7(7.4X)

Speedup sort strings with length equal to fundamental types:
 - 1 bytes in 7 times
 - 2 bytes in 14 times
 - 4 bytes in 11 times
 - 8 bytes in 8.5 times

Speedup through optimize of comparison of static strings:
 - length is a multiple of two speedup in 2 - 2.5 times
 - length is a multiple of four speedup in 3 - 3.5 times
