support: Expose TEST_VERIFY_EXIT behavior to GCC optimizers

Browse Source 
Previously, the implementation would conditionally exit based on the
status argument, which GCC did not know about.  This leads to
false uninitialized variable warnings when data is accessed after a
TEST_VERIFY_EXIT failure (from code which would never execute).
