[libcxx] r177892 - Debug mode: learning to crawl. I need to set up some tests that actually test that the debug mode is working, but that won't cause problems when debug mode isn't on.

Hi Howard,

Maybe I'm missing something, but why go through std::terminate when
you can put std::exit(0) here:

> +#define _LIBCPP_ASSERT(x, m) ((x) ? (void)0 : std::terminate())
