Cycles: Speedup transparent shadows on CUDA

Browse Source 
This commit enables record-all behavior of transparent shadows
rays.

Render times difference goes as following:

               GTX 1080 render time
BMW                  -0.5%
Fishy Cat            -0.0%
Pabellon Barcelona   -11.6%
Classroom            +1.2%
Koro                 -58.6%

Kernel will now use some extra VRAM memory to store the intersection
array (200MB on my configuration). This we can optimize out with some
further commits.
