1. Linear gradients were considered equal if the first gradient has no x and y
   position and the second has no x but does have y.
2. Same as 1, for radial gradients. (This doesn't happen in practice as
   CSSParser::parseRadialGradient rejects such input, so no test for this case.)
3. Radial gradients without x and y position weren't considered equal even if
   they were.

Patch by Alexander Shalamov <alexander.shalamov@intel.com> on 2013-02-11
Reviewed by Antti Koivisto.

Source/WebCore:

Added comparison method to CSSValue and its children, so that the
css values could be compared efficiently. Before this patch, CSSValue
objects were compared using strings that were generated by the cssText() method.
