Add a getter for the attributes of
Object.defineProperty, and use it in three places:DataFlow::ObjectDefinePropertyAsPropWrite::getRhs: improve dataflow expressivity (does not impact performance: definitions, XSS/gecko)ExprHasNoEffect::isGetterProperty: sharpen whitelist (no changes)DeadStoreOfProperty: only flag a call toObject.definePropertyif it includes a value (eliminates some FPs, the new result has been eliminated now)
