There was a ton of complicated logic here to work around two problems: - Same-type constraints were not represented properly in RequirementReprs, requiring us to store them in strong form and parse them out when printing type interfaces. - The TypeBase::getAllGenericArgs() method did not do the right thing for members of protocols and protocol extensions, and so instead of simple calls to Type::subst(), we had an elaborate 'ArchetypeTransformer' abstraction repeated in two places. Rewrite this code to use GenericSignatures and GenericFunctionType instead of old-school GenericParamLists and PolymorphicFunctionType. This changes the code completion and AST printer output slightly. A few of the changes are actually fixes for cases where the old code didn't handle substitutions properly. A few others are subjective, for example a generic parameter list of the form <T : Proto> now prints as <T where T : Proto>. We can add heuristics to make the output whatever we want here; the important thing is that now we're using modern abstractions.
