NOTREACHED() and NOTREACHED_IN_MIGRATION() are both CHECK-fatal now.
The former is [[noreturn]] so this CL also performs dead-code removal
after the NOTREACHED().
This CL does not attempt to do additional rewrites 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.
