libstdc++ 11.1.0 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.
