Previously IRGen was using a heuristic to assign the argument number to the $error variable that was not generally correct for optimizaed code. This patch inserts a debug_value instruction in SILGen and thus assigns the ArgNo together with all the other function arguments. This is more robust and faster than than the old heuristic. <rdar://problem/28748323>
