Remove pointless statements

If we have the following code in our JSX components:

if (process.env.COMPILER === 'react') {
  console.log('i am in react');
}
if (process.env.COMPILER === 'vue') {
  console.log('i am in vue');
}

the compiled code in, for example, Vue component, will be:

if ('vue' === 'react') {
  console.log('i am in react');
}
if ('vue === 'vue') {
  console.log('i am in vue');
}

which doesn't make much sense. So we need to walk through such simple literal conditions and remove/modify them to:

in react we should have only:

console.log('i am in react');

and in vue:

console.log('i am in vue');
