Incorrect transformation to arrow function when using this for a default parameter value

[isuro]

Describe the bug

When minifying a method on an object that uses this for a default value of a parameter, swc incorrectly transforms the method to an arrow function. This is because it doesn't detect any use of this in the method body, but this is valid:

foo(a = this.bar) {return a}
