This patch rewords the static assert diagnostic output. Failing a _Static_assert in C should not report that static_assert failed. This changes the wording to be more like GCC and uses "static assertion" when possible instead of hard coding the name. This also changes some instances of 'static_assert' to instead be based on the token in the source code. Differential Revision: https://reviews.llvm.org/D129048
