Automatic update from web-platform-tests CSS calc function should evaluate and parse infinity and NaN According to the newest version of CSS standard [1], calc function could return an infinity or NaN value when the expression has an infinity keyword without NaN product (like inf-inf) or the division by zero. Therefore, this initial feature implementation evaluate the expression or keywords infinity value to std::numeric_limits<double>::infinity() and NaN value to std::numeric_limits<double>::quiet_NaN(). Also, this patch contains the infinity and NaN value serialization.
