Minify: Array destructuring issue

[zamb3zi]

This is very similar to #151 and is occurring on the current master version.

Input

function foo(arg) {
    const {
        x: [x],
        y: [y],
    } = arg;
    return x;
}

Output

function foo(a){return b}

REPL

Compared with the following correct behaviour:

Input

function foo(arg) {
    const {
        x: [x],
        y: [y],
    } = arg;
    return x + y;
}

Output

function foo(a){const{x:[b],y:[c]}=a;return b+c}

Interesting. Thanks. Looks like a bug in DCE. Will try this.

Fixed by #622

Confirmed, my test cases are now working.
