cuSparse libraries on windows encode the cuda version in the
DLL names. This commit adds the suffixes to the cuSparse module
class

Ccache has support for windows. This seems to work with the Windows
binaries of the ccache program with the Ninja generator. I don't

Catch OpenCL errors when creating Contexts from OpenCL devices.
This change is necessary because some platforms(Intel FPGA) were
crashing if certain environment variables were not set when
crating contexts even though the platform returned the device
from the platform. We catch errors for particular devices and
then we remove them from the device list.
