      Optimized vector composite ops by 1.5-2 times more · 72c50366
      Dmitry Kazakov authored
      Conversion Uint<->Float is quite expensive in comparison to
      Int<->Float (2-2.5 times). This happens because of special code
      that handles sign bit of the number. So discarding this bit with
      conversion Uint->Int makes a huge speedup.
      
      Now the vector version of the composition is 1.8-8.7 times faster
      that the old version (weighted: 3.2 times).
      
      Many thanks to Matthias Kretz for pointing this out!
