Hello Faisal. Lots of buildbots have failed after your commit "[c++2a] [concepts] Add rudimentary parsing support for template concept declarations" (rC330794)

Fix buildbot problems after https://reviews.llvm.org/rC330794 Avoiding error: no matching function for call to 'makeArrayRef' at ../tools/clang/lib/Parse/ParseTemplate.cpp:373:17 By using a local C array as input to makeArrayRef. Not sure if this is the best solution, but it makes the code compile again.
