e106d336cb while I'm in a cleanup mood, move the factory functions from 
types off of ASTContext onto the types themselves.  This 
never made sense for clang, and makes the same amount of sense
for swift.  Start with function types.

could be handled in similar ways, this gets the most of them.

9e8c82435a implement AST and sema support for methods. The example method in the 
testcase now AST's to:

   (methdecl 'print2' type='(this : rect) -> (os : ostream) -> ()'
      (closure_expr type='(this : rect) -> (os : ostream) -> ()'
        (closure_expr type='(os : ostream) -> ()'
          (brace_expr type='()'
            (apply_expr type='int'
              (declref_expr type='(r : rect) -> int' decl=area)
              (tuple_expr type='(r : rect)'
                (declref_expr type='rect' decl=this)))))))

which seems right.  Some cleanups are pending.

6720390c84 Implement a first, very simple cut at ranking conversions for overload sets. This is important because we previously required exact type matching for overload resolution, and (int) != (.x : int) so no arguments with names would match up with anonymous values. 
We still don't use ranking for binary operators etc.

3b4a8b03d2 1. With overloading in play, SemaDecl should never resolve unqualified lookup that hits at translation unit scope to a DeclRefExpr. Doing so can break overloading. 
2. This exposed a bug: when parsing structs, we weren't adding all decls to the translation unit, we were just adding the type alias.
3. This exposed that TypeChecking wasn't handling OneOfElementDecl.
4. Introduce a new NLKind enum in NameLookup instead of passing around a bool.
5. Have unqualified lookup that returns an overload set form a new OverloadSetRefExpr, which has dependent type.
6. Enhance various stuff to handle OverloadSetRefExpr.  It's still not fully handled yet though, so it can't be used for anything useful.
7. Change Expr.cpp to print types with << instead of T->print(OS) which is simpler and correct in the face of null.

5e28a6fcdd Finally get around to doing a major type system refactoring, where we introduce Type as a "smart pointer" and rename the existing Type class to TypeBase. 
This prevents use of isa/dyn_cast/etc on Type*'s and means we just pass around Type by value instead of having to use Type* everywhere.

7530ec988c Add a error to reject foo() when foo is not a function type. Previously we allowed it because these are two valid top-level values, but we now reject them because they are almost certainly a bug. This can be disabled by putting a space between them if this is useful for some reason.

c9ee19e269 Implement parser, sema, doc, and name lookup support for refined import declarations. You can still only do top level references, but that's because we don't have namespaces or anything else interesting yet.

aeb7c0895e The isGroupingParen() predicate doesn't make sense since TupleExpr can be used to create tuple expressions out of a scalar when there is a single element involved. In this case, isGroupingParen would return true but the source and dest types would be different. 
This didn't manifest as a bug yet, but it doesn't make sense to wait until it does.  This aspect of grouping parens is a syntactic issue, so make the creator of TupleExpr specify whether the expr is a grouping paren or not and persist this.
