It actually needs to come first because JS-style assignments should not hit the computed property check. It won't be very expensive because most declarations are not in javascript files and even there, most declarations are not JS-style assignment declarations.

Now Javascript-style declarations like
this.foo = "bar"are handledcorrectly and errors will be reported on the declaration correctly. Previously the code would check the computed property name case and crash because Javascript-style declarations have no
nameproperty.Fixes #15525
