; modify_value will be inlined into main. With just the inliner pass, at most 
; some trivial DCE would happen, which in this case doesn't modify post-inlined
; main much.
; In contrast, with the full set of module inliner-related passes, at the end of
; inlining (incl. function cleanups ran after inlining), main will be reduced to
; a 'ret 10'
