g_assert_true(), g_assert_cmpint(), and friends, can return to the
caller if test_nonfatal_assertions is set, but this is normally not the
case. In particular, for the purposes of static analysis, we
specifically don't want to assume that they might return. Clang has an
analyzer_noreturn attribute for this exact purpose, which conveniently
already has a macro in gmacros.h.
