ARROW-90: [C++] Check for SIMD instruction set support This also adds an option to disable the usage of a specific instruction set, e.g. you compile on a machine that supports SSE3 but you want to use the binary also on machines without SSE3. (Distribution packagers will love that option!) Author: Uwe L. Korn <uw...@xhochy.com> Closes #50 from xhochy/arrow-90 and squashes the following commits: 6fd80d3 [Uwe L.
