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.
