93ac2b3cb9 rename FuncExpr to LambdaExpr.

a8e2788184 implement semantic analysis for FuncExpr and have the parser lower func decls
to func exprs.  All the tests pass again.  Now we have a strict equality 
between:

  func foo(a : int) -> int { a+1 }

and 

  var foo = func(a : int) -> int { a+1 }

except we don't support the later syntax yet.  We also really need return, though
we're getting closer to being able to usefully support it.

63ce0be641 make the big switch: {} are now statements, not expressions. This removes some
annoying things from the grammar (like expr-non-brace), and makes it so that 
the body/else of an if is just a statement.

This patch has a fairly serious caveat that we just drop function bodies on the
floor now, since we have no "stmtexpr" sort of thing to represent the syntactic
sugar that is func.  We'll fix that soon.

0fc77abf5c Per discussion on swift-dev, unify 'meth' and 'func' syntax into just 'func' syntax
where you can optionally declare a receiver type.  This is cleaner both conceptually
and in implementation, and eliminates drug references. :)

IntegerLiteral to IntegerLiteralExpr, which is good for consistency anyway.

096a3e16bc switch to range-based for loops where possible. I'm actually surprised how many
places are blocked by needing an index exposed for other purposes.  Not having a
MutableArrayRef doesn't help either.

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.

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.
