60e5ebdd62 Fix Cycles CUDA kernels for Ampere not building with CUDA 11 
Running Blender on Ampere cards was already possible with ptx, this fix is
needed to support building CUDA binaries.

Note the CUDA version used for official Blender builds is still 10, this is
merely the change to make it possible for those using CUDA 11 and specifying
the sm_8x kernels to be compiled.

Found by Milan Jaros.

b14ec18601 Cycles: add initial CUDA 10.0 support, but only recommend use for Turing cards. 
There may still be rendering errors when used for older graphics cards.

1febc85855 Cycles: Workaround for performance loss with the CUDA 9.0 SDK. 
CUDA 9.0.176 apparently caused some slow down on high-end Pascal cards that can be mitigated by increasing the number of registers. See https://developer.blender.org/F1142667 for a detailed comparison.

45dcd20ca9 Cycles: CUDA split performance tweaks, still far from megakernel. 
On Pabellon, 25.8s mega, 35.4s split before, 32.7s split after.
