This patch corrects an error in the compiler whereby no
Corresponding_Spec was set for emptied CUDA global subprograms - leading
to a malformed tree.
Tested on x86_64-pc-linux-gnu, committed on trunk
gcc/ada/
* gnat_cuda.adb (Empty_CUDA_Global_Subprogram): Set
Specification and Corresponding_Spec to match the original
Kernel_Body.
