[CUDA] Work around compatibility issue with libstdc++ 11.1.0 

libstdc++ redeclares __failed_assertion multiple times and that results in the
function declared with conflicting set of attributes when we include <complex>
with __host__ __device__ attributes force-applied to all functions.

In order to work around the issue, we rename __failed_assertion within the
region with forced attributes.

See https://bugs.llvm.org/show_bug.cgi?id=50383 for the details.
