Artem Belevich 7b41f70e6c [CUDA] __global__ functions should always be visible externally. 
Adjust __global__ functions with DiscardableODR linkage to use
StrongODR linkage instead, so they are visible externally.

Artem Belevich c3fa25def7 [CUDA] Add implicit __attribute__((used)) to all __global__ functions. 
This makes sure that we emit kernels that were instantiated from the
host code and which would never be explicitly referenced by anything
else on device side.

Artem Belevich b7e4aab40c [CUDA] Add implicit __attribute__((used)) to all __global__ functions. 
This allows emitting kernels that were instantiated from the host code
and which would never be explicitly referenced otherwise.

Peter Collingbourne a9455ec9f8 CUDA: add -fcuda-is-device flag
