value. This is on by default, and controlled by -Wreturn-type (-Wmost
-Wall). I believe there should be very few false positives, though
the most interesting case would be:
int() { bar(); }
when bar does:
bar() { while (1) ; }
Here, we assume functions return, unless they are marked with the
noreturn attribute. I can envision a fixit note for functions that
never return normally that don't have a noreturn attribute to add a
noreturn attribute.
If anyone spots other false positives, let me know!

This fixes <rdar://problem/6839489> 10A345: Clang does not warm about mismatched returns (void return from a bool function)
Will implement -Wreturn-type, -Wno-return-type in another commit.
