CL 395541 made staticopy safe, stop applying the optimization once seeing an expression that may modify global variables. However, if a call expression was inlined, the analyzer mis-recognizes and think that the expression is safe. For example: var x = 0 var a = f() var b = x are re-written to: var x = 0 var a = ~r0 var b = 0 even though it's not safe because "f()" may modify "x". Fixing this by recognizing OINLCALL and mark the initialization as not safe for staticopy.
