This removes unreachable return statements as diagnosed by
the -Wunreachable-code patch. Some cases are more obviously
an improvement than others - in fact some may get you the idea
to replace them with gcc_unreachable () instead, leading to
cases of the 'Remove unreachable gcc_unreachable () at the end
of functions' patch.
Bootstrapped and tested on x86_64-unknown-linux-gnu.
OK? Comments? Feel free to approve select cases only.
Thanks,
Richard.
