OpenGL docs specifically insist that the sequence (comma) operator should not be treated as a constant-expression so that attempts to declare multidimensional arrays with a comma will fail: http://screen/vJEpAe9yNmbzZTm (See "12.43 Sequence operator and constant expressions" in the OpenGL ES3 documentation or read skia:13311 for details.) In practice, we don't get much benefit from optimizing away unused comma-expressions; it improves some synthetic tests, but realistically this will not help Skia in any real-world scenario. The constant folder no longer attempts this optimization, and comma-expressions are now rejected in a constant-expression context.
