[css-grid] Simplify grid track sizes parsing
https://bugs.webkit.org/show_bug.cgi?id=158021
Reviewed by Sergio Villar Senin.
Previously once we saw an auto-repeat function,
we passed the "FixedSizeOnly" restriction to the rest of methods.
That way we were sure that all the tracks after the auto-repeat
had fixed sizes.
But we needed to call allTracksAreFixedSized() to be sure that
the tracks before the auto-repeat had fixed sizes too.
Now we're introducing a new boolean |allTracksAreFixedSized|,
to check in advance if the declaration contains any track not fixed.
If that's the case and we found an auto-repeat method,
we consider it invalid.
With this approach we avoid the loop to verify
that all the tracks (before and after the auto-repeat) are fixed.
It also allows us to simplify the code and avoid passing
the restriction to all the methods parsing the track size.
No new tests, no change of behavior.
* css/CSSParser.cpp:
(WebCore::isGridTrackFixedSized): New method to check if a grid track
size is fixed or not (based on old allTracksAreFixedSized()).
(WebCore::CSSParser::parseGridTrackList): Add new boolean to detect
if any track has not a fixed size.
(WebCore::CSSParser::parseGridTrackRepeatFunction): Ditto.
(WebCore::CSSParser::parseGridTrackSize): Remove usage of
TrackSizeRestriction enum.
Check here if |minTrackBreadth| is a flexible size.
(WebCore::CSSParser::parseGridBreadth): Remove usage of
TrackSizeRestriction enum.
(WebCore::allTracksAreFixedSized): Deleted.
* css/CSSParser.h: Remove TrackSizeRestriction enum and update headers.
