Minifier inlines hoisted var variable usage incorrectly

[hyp3rflow]

Describe the bug

The hoisted var variable can be accessed without ReferenceError, but its value is undefined before initialization.
Currently minifier doesn't care about this and inlines it using the invalid value in declaration statement.

Input code

function foo() {
  const a = x;
  var x = 42;
  return a;
}

console.log(foo())
