This patch changes `EmitPPCBuiltinExpr` in `CGBuiltin.cpp` to remove the loop at the beginning of the function that emits the arguments and to delay emitting the arguments until inside the switch statement. These changes will put `EmitPPCBuiltinExpr` in line with the strategy of the target independent function `EmitBuiltinExpr`. Also, this patch ensures that arguments are only emitted once. Tests that included builtins affected by these changes have been modified to match expected behaviour.
