09a023c3cd Now that we have simple user defined data types, remove the __builtin_else_hack type. woot.

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.

9ba168ace5 Fix Alias uniquing to reuse the already-uniqued identifier object instead of being a string map. Make getAliasType fail if a redefinition happens and make getNamedType return datatype's as well.

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)

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;

This also eliminates TupleConvertExpr.

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.

422da5de1f Give _0 a dependent type and use type inference to determine what it is based on context. Still some "bottom up" type inference logic missing, and we don't infer all the types in the expression tree of things like: 
func6((_0 4) + _0);

yet.

667078650a Implement support for anonymous closure arguments. For example, we can now compile this: 
var func6 : ((int,int) -> int) -> ();  // Takes a function, returns nothing.
func funcdecl5() {
  func6(_0 + _1);         // Closure with two named anonymous arguments
}
into:

  (apply_expr type='()'
    (declref_expr type='(int, int) -> int -> ()' decl=func6)
    (closure_expr type='(int, int) -> int'
     (anondecl '_0' type='int')
     (anondecl '_1' type='int')
     (tuple_expr type='int'
      (binary_expr '+' type='int'
       (declref_expr type='int' decl=_0)
       (declref_expr type='int' decl=_1))))))))

However, there are still some problems with this (and we're definitely not doing type inference yet, all anon args are assumed 'int').

874421d4ce Implement AST and Sema support for auto-closures. We now parse: 
var closure1 : () -> int = 4;  // Function producing 4 whenever it is called.
var closure2 : (int,int) -> int = 4; // Has some (dead) arguments.

into:

(vardecl 'closure1' type='() -> int'
 (closure_expr type='() -> int'
  (integer_literal type='int' value=4)))
(vardecl 'closure2' type='(int, int) -> int'
 (closure_expr type='(int, int) -> int'
  (integer_literal type='int' value=4)))

2bafb0e8fb Introduce new NamedDecl and FuncDecl classes. The difference between the two is syntactic sugar, so most clients want NamedDecl. This doesn't implement FuncDecl yet, which isn't a high prio for me in the short term.
