Test case: metaprogram to remove void from a parameter pack

The attached code causes clang to crash with a segmentation fault.

Commands used:
  time clang++ -std=c++11 -c test.cpp -o /dev/null -ftemplate-depth=10000
    -> result: crashes after 21s
  time g++ -std=c++11 -c test.cpp -o /dev/null -ftemplate-depth=10000
    -> result: compiles correctly within 0.6s
