154c0c6eb9 Resolve a fixme by eliminating the ; in func decls and making the grammar more restrictive.

b9fbd77f58 Fix a bunch of minor bugs found through inspection: 
1. Punctuation identifiers were missing some characters.
2. Some parser production and methods were misnamed.
3. Top level var decls don't need a ; after them.
4. Various parser comments were out of date.
5. We now allow any type in a struct decl, e.g. "struct foo int", even though it's weird.

a885cd5dc5 Diagnose completely unresolved expressions with an error like this: 
data.swift:114:10: error: ambiguous expression could not resolve a concrete type
var xx = :Zero;
         ^

Do this with a very general pre/post-order walking function.

ad438c55e3 Implement the rest of sema for scoped identifier references (X::Y) we now get a proper DeclRefExpr, and this: 
var def = DataSearchFlags::None;

-ast-dump's into:

(vardecl 'def' type='DataSearchFlags'
 (declref_expr type='DataSearchFlags' decl=None))

ac855b690b Move ActOnTypeAlias to SemaDecl since a type alias *is* a decl that *installs* a type. Add some fixme's and rename some junk in ASTContext relating to the typemap. Diagnose redefinitions of named types. Install a typemap entry when a data declaration is defined. 
We can now declare variables to be of data type.

d2abfde434 introduce a new builtin type to represent the result of the else binary operator (which is a temporary hack until we get user defined types). 
Use it to define ife/else.  Fix some precedence/parsing bugs that implementing else exposed.

d5f834512e Next step to allow use of named arguments: Create a new ArgDecl AST node, and have SemaDecl form them. We now correctly diagnose argument name redefinitions (though the diagnostic sucks because we don't have loc info)

bf63029ecd rework tuple element parsing to not use ParseDeclVar, since tuple elements are fundamentally different. While we're at it, switch to an arguably more natural syntax for field elements, naming them with .x : type instead of var x : type

f704c58c42 Two significant changes: 
1. Change the representation of TupleType to contain TupleTypeElt structs instead of PointerUnion<Type*, NameDecl*>
 2. Change type canonicalization to not strip field names off tuples, and change type conversion logic to use canonical types again.

Also adds some stuff to the todo list, destined to never be short.

04f7a08621 add support for tuple field access with ".", e.g.: 
var a : (int, var f : int, int);
  var b = a.field0+a.field1+a.f;

1bb344c282 strength reduce our handling of dependent types. Now, you can't compose dependent types, there isn't a (dep, int) type, the whole tuple gets dependent type. This simplifies things a bit.

7a5b428772 start reworking tuple compatibility: two different tuples aren't compatible because their canonical type is the same, they are compatible because one can be converted to the other. I'm just going to rip out canonical type support for now.
