Adds a required class

@param name {String} the name of the class
@param opts {Map?} which is:

@param where {"ignore"|"require"|"use"|null} where it's mentioned
@param load {Boolean?} whether it is a load-time dependency or not
@param defer {Boolean?} whether the dependency is in defer or not
@return {Map?} info about the symbol type of the named class, @see {Analyser.getSymbolType}
