+Subject: restore _Noreturn to __assert_fail
+
+this reverts commit 2c1f8fd5da3306fd7c8a2267467e44eb61f12dd4. without
+the _Noreturn attribute, the compiler cannot use asserts to perform
+reachability/range analysis. this leads to missed optimizations and
+spurious warnings.
+
+the original backtrace problem that prompted the removal of _Noreturn
+was not clearly documented at the time, but it seems to happen only
+when libc was built without -g, which also breaks many other
+backtracing cases.
