Add no-plusplus rule autofixer

There is a no-plusplus rule. Let’s add an autofixer for the rule.

http://eslint.org/docs/rules/no-plusplus

What rule do you want to change? no-plusplus

Does this change cause the rule to produce more or fewer warnings? amount of warning won’t change

How will the change be implemented? (New option, new default behavior, etc.)? autofixer to no-plusplus will added

Please provide some example code that this change will affect:

var foo = 0; foo++;

will be fixed to

var foo = 0; foo += 1;

What does the rule currently do for this code? this rule does nothing, because there is no autofixer

What will the rule do after it’s changed? fix code as shown above

• ESLint Version: 3.8.1

Please note i++ and i+=1 has different return values. I think we cannot autofix i++ if the return values are used.

It looks like we decided not to merge https://github.com/eslint/eslint/pull/7514, so I’m going to close this issue.
