[BUG] Variables from dead else-if branch are hoisted to incorrect location

[shrinktofit]

#3752 did not consider such case:

if (globalThis.notDead) {
    console.log('true-branch');
} else if (false) {
    var w; // `const` works fine here
    console.log('else-if-branch');
} else {
    console.log('else-branch');
}

which incorrectly outputs:

if (globalThis.notDead) {
    console.log('true-branch');
} else var w; {
    console.log('else-branch');
}

The "incorrect" here is that w is unused, otherwise the code is valid and working?

Edit: Ah sorry, misread the output

Thanks for spotting, fix at #3782.
