Ramiro Polla 2d1358a84d swscale/range_convert: saturate output instead of limiting input 
For bit depths <= 14, the result is saturated to 15 bits.
For bit depths > 14, the result is saturated to 19 bits.

NOTE: all simd optimizations for range_convert have been disabled
      except for x86, which already had the same behaviour.
      they will be re-enabled when they are fixed for each architecture.
