Summary: TI+JM: correctness bug with x && arguments → TI: correctness bug with x && arguments
Braindead bug, when analyzing whether a use of 'arguments' escapes and seeing it flow to a phi node, we would analyze the uses of the components of the phi rather than the phi itself. http://hg.mozilla.org/projects/jaegermonkey/rev/0f02561d061c
