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.
