[PATCH] D31966: [libcxx] [test] Avoid Clang's -Wunused-const-variable in is_constructible.pass.cpp.

[Stephan T. Lavavej via Phabricator via cfe-commits]

STL_MSFT created this revision.

[libcxx] [test] Avoid Clang's -Wunused-const-variable in 
is_constructible.pass.cpp.

This happens when using Clang with MSVC's STL, so there are no actual uses of 
this variable.
