Fixes mypyc/mypyc#879
Changed the type of exception that is raised on undefined names from
RuntimeErrortoNameError.Moved the runtime error that refers to unexpected execution of unreachable code to
shortcircuit_exprto keep existing behavior and generate the exception in blocks that are unreachable due to short-circuiting.In the future this could probably be optimized to not generate any code at all and just constant-fold the boolean expression.
