Cycles Refactor: Add SSE Utility code from Embree for cleaner SSE code.

This makes the code a bit easier to understand, and might come in handy
if we want to reuse more Embree code.

Differential Revision: https://developer.blender.org/D482

Code by Brecht, with fixes by Lockal, Sergey and myself.
