Attempt to fix #36935 : disable SSE optimizations on 32 bit windows too. Something
...
strange is going on here, but I don't think it can be fixed before the release,
if it is worth at all spending time on this.

Fix #36316 : dots in cycles render on certain CPUs with 32 bit linux builds.
...
There is some sort of problem with the SSE2 code path, but I couldn't find
the cause, maybe a compiler bug due to the large amount of inlining? For
now I've disabled SSE2 optimizatons in 32 bit GCC builds.

without SSE3 support, due to 80 bit precision float register being used for one
bounding box but not the one next to it.

Fix #29259 : cycles issues on certain processors. Now two versions of the kernel
...
are compiled, one SSE optimized and the other not, and it will choose between
them at runtime.

Cycles uses code from some great open source projects, many thanks them:
* BVH building and traversal code from NVidia's "Understanding the Efficiency of Ray Traversal on GPUs":

* Open Shading Language for a large part of the shading system:

* Blender for procedural textures and a few other nodes.
* Approximate Catmull Clark subdivision from NVidia Mesh tools:
