My preference would be to turn -Wreturn-type on by default, but not
create the separate -Wmissing-return flag. As I argued in 2002, there
should only be one flag.
To avoid spurious warnings on code with infinite loops we could add a
simple check for infinite loops and suppress the warning in that case.
Basically, if we see a loop with an always-true condition and no breaks.
