[BUG] Multiple increments or decrements of the same field don't combine together

[michaelboyles]

Describe the bug

Multiple increment and decrement operators don't combine together properly. Increment followed by decrement should no-op, but currently the second operation just gets dropped. Multiple increments or decrements in a row should accumulate.

Sample input

interface State {
    val: number;
}
const reducer = redcr((state: State) => {
    state.val++;
    state.val--;
});

Current output

Specify which ES version you're targeting: ES2020

const reducer = (state) => {
    state = {
        ...state,
        str: state.str + 1
    };
    return state;
};
