2711ad03c9 now that WalkOrder is in a common header, move the WalkStmt to be a
Stmt method, rename it to just 'walk' to follow the naming convention,
and give it an accurate doc comment for good measure.

cb59d9c926 split the walkorder enum out to its own header file. This is a silly waste of
a file, but is needed to share it between two other heads.  Header files seem
so baroque.

1dc200c973 introduce an official ErrorType. This is to be used when a type is incorrectly
constructed.  When put on a decl, this should cause all uses of the decl to 
collapse away into badness during type checking.

10f5c2fc66 remove the UnresolvedType, representing it with a null Type() instead. There is no need to
have two different ways to represent the same thing.  This has the pleasant bonus that stuff
crashes when you do things with unresolved types.

433d6de807 implement AST and parser support for 'return'. We're still not doing a conversion
to a return type yet though.  We happily diagnose thigns like this as an error:

func foo() -> int {
  return 4 5
}

350b89e6e4 Represent assignments as their own AssignStmt, preserving the model we had
before, but removing the hack where we'd represent them as a binary operator
with a null operator function.  We still have no clear semantics for what 
is valid or not.

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. :)

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.
