This change makes two big adjustments.  * Be a lot more accurate about what the effects will be when inlining a call    to a function when an argument is an alloca.  * Dramatically reduce the penalty for inlining a call in a large function.    This heuristic made it almost impossible to inline a function into a large    function, no matter how small the callee is.
