History
Richard Biener 16507dea75 Remove unreachable returns 
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.
