Can use KNOWN_LEAKING; to specify that a test is known to leak memory.
The location information is available in regular game builds. Thus it is
available for use in debugging leaks in-game too. In the future we
should consider replacing it with NULL if NDEBUG is defined. This is not
currently possible because the tests do not force NDEBUG to be
undefined.
* Build tools for check
* Display PASSes when Hydra exits
* Print buffered output at exit
* Remove unused test summaries
* Show SKIP if ASSUMPTIONS fails
