[minifier] Incorrect minification with a bigint value created by a binary operator inside conditions

[sapphi-red]

Describe the bug

(a | b) === 0 is compressed into (a | b) == 0 and causing the code to behave differently after minification.

Input code

export function foo(a, b) {
  if ((a | b) === 0) {
    throw new Error()
  }
}

SWC Info output

No response

Expected behavior

The output is

export function foo(o,r){if((o|r)===0)throw Error()}

Actual behavior

The output is

export function foo(o,r){if((o|r)==0)throw Error()}

For anyone wondering with which input these aren't equivalent (like me): BigInts.

function foo(a, b) {
  return (a | b) === 0
}

function foo2(a, b) {
  return (a | b) == 0
}

console.log(foo(0n, 0n)) // false
console.log(foo2(0n, 0n)) // true

Ah, my bad, I thought I wrote it.

swc minifier hasn't been prepared for BigInt yet. Another example would be #9938.
