Add all of the Objective-C methods in the given Objective-C container to the set of results.

The container will be a class, protocol, category, or implementation of any of the above. This mether will recurse to include methods from the superclasses of classes along with their categories, protocols, and implementations.

Parameters
Containerthe container in which we'll look to find methods.
WantInstanceMethodsWhether to add instance methods (only); if false, this routine will add factory methods (only).
CurContextthe context in which we're performing the lookup that finds methods.
AllowSameLengthWhether we allow a method to be added to the list when it has the same number of parameters as we have selector identifiers.
Resultsthe structure into which we'll add results.

If we're in a C++ virtual member function, add completion results that invoke the functions we override, since it's common to invoke the overridden function as well as adding new functionality.

Parameters
SThe semantic analysis object for which we are generating results.
