[cleanup] Remove unnecessary ClassifyAndRewriteReferenceExpression method

[cleanup] Remove unnecessary ClassifyAndRewriteReferenceExpression method

Now that the destructuring flags are gone, we always call
CheckAndRewriteReferenceExpression, so unified the two methods again.
Also cleaned up the code within, e.g. removing unnecessary Scanner::Location
construction.
