Migrate NOTREACHED_NORETURN -> NOTREACHED

NOTREACHED() has turned [[noreturn]] so the former macro isn't needed
anymore.

This does not attempt to do a rewrite of any surrounding code, like:

if (!foo) {
  NOTREACHED();
}

to CHECK(foo);

Those transforms take a non-trivial amount of time (and there are
thousands of instances). Cleanup can be left as an exercise for the
reader.

NO_IFTTT=No-op-rename migration.
