columnar_serialization: fix optimized GCC build

It seems that GCC with -O1 or higher is less lenient about the pointer
types passed as the first argument to the _mm_gather* intrinsics. This
was causing the Ubuntu 18 release build to fail.

I was able to reproduce the failure and fix on my own Ubuntu 18 box
using a fastdebug build.
