[PATCH] D21350: [libcxx] [test] Avoid C++17 terse static_assert.

TOTALLY OPTIONAL, feel free to reject this, I won't mind.

Newly-added libcxx tests for C++17 features have been using C++17 terse static_asserts occasionally. This is problematic for MSVC at the moment, since the compiler doesn't yet support the terse form. Changing the tests to always use the original recipe static_assert instead of extra crispy allows them to pass when we have the corresponding library support.

MSVC will be gaining support for the terse form soon, which will make this a non-issue for me, but I wanted to send out this change just in case you thought it was a worthwhile improvement in consistency.
