https://github.com/miloyip/itoa-benchmark/blob/940542a777015 5ee3e9f2777ebc178dc899b43e0/src/branchlut.cpp

I have implemented super-fast conversion routines:

https://github.com/ultimatepp/ultimatepp/blob/1d018151f105f4 e739045307577e3dd0bc8b856a/uppsrc/Core/Format.cpp#L75

AsString(int) should now be about 8 times faster than before.
