Instead of 95, we can use 145 images now. This only affects Kepler and above (sm30, sm_35 and sm_50).
This can be increased further if needed, but let's first test if this does not come with a performance impact.
Originally developed during my GSoC 2013.
This fixes the SSS Direct/Indirect passes as well as the Combined pass.
Patch reviewed and with fixes and contributions from Brecht van Lommel.
Note: displacement/bump map (related to the report) will be handled separately

Now the COMBINED pass includes the Ambient Occlusion.
This was not reported anywhere, but while working in the Subsurface Scattering I realize we needed this fix for combined.
This was faster for my AMD system but slower for Intel.
However with gcc4.9,-O3 I was able to get roughly the same speed before/after.
Revert since this isnt giving such clear benefits on most systems.
Expand Cycles to use the new baking API in Blender.
It works on the selected object, and the panel can be accessed in the Render panel (similar to where it is for the Blender Internal).
It bakes for the active texture of each material of the object. The active texture is currently defined as the active Image Texture node present in the material nodetree. If you don't want the baking to override an existent material, make sure the active Image Texture node is not connected to the nodetree. The active texture is also the texture shown in the viewport in the rendered mode.
Remember to save your images after the baking is complete.
Note: Bake currently only works in the CPU
Note: This is not supported by Cycles standalone because a lot of the work is done in Blender as part of the operator only, not the engine (Cycles).

Original design by Brecht van Lommel.

Probably will not be noticed in most scenes. This helps reduce noise when you
have multiple lamps with MIS enabled, at the cost of some performance, but from
testing some scenes this seems better.
The was actually caused by the way how Cycles uses objects
layers. It's not possible to rely on the fact that layers
are flushed from Base to Object. It's only valid when rendering
active scene.
Now made it so layers are used from the base.
This also updates the configurations to build kernels for compute capability
5.0 cards, when using and older CUDA toolkit version this will be skipped.
Also includes tweaks to improve performance with this version:
* Increase max registers on sm_30, sm_35 and sm_50
* No longer use texture storage on sm_30
The formula was not consistent across Blender and behaved strangely, now it is
a simple linear blend between color1 and min(color1, color2).
