<pre>Compiling C++11 template code with `>>>` fails in some cases as soon as `-x
cuda` is used.
Although `>>>` should be valid in C++11, they might be mismatched here with
CUDA kernel arguments.
Environment:
clang version 7.0.0 (<a href="https://git.llvm.org/git/clang.git/">https://git.llvm.org/git/clang.git/</a>
780143bbd516aa39d754e5cab50955321b71fba0) (<a href="https://git.llvm.org/git/llvm.git/">https://git.llvm.org/git/llvm.git/</a>
bef5f248b85fb47702bd94a11276728a4cb4689f)
nvcc 8.0.44
It would be great if closing multiple nested template arguments in such manner
works with the CUDA frontend as well.
Reproducer: Issue first seen with Boost.mp11 (1.66.0) with minimal example:
#include <boost/mp11.hpp>
int main() {}
Compiled with
clang++ -std=c++11 -x cuda main.cpp --cuda-path=$CUDA_ROOT
-I$BOOST_ROOT/include

We could not boil it down to a non-mp11 code snippet yet, maybe it's related to
the heavy use of variadic template arguments in combination with `>>>` ?</pre>
