Automatic update from web-platform-tests Make calc() function can be used in any place that only accepts integer. https://www.w3.org/TR/css-values-4/#calc-type-checking spec says that calc() function that resolve to <number> can be used in any place that only accepts <integer>. This change makes calc() function's behavior to comply with the spec.
