f9673bb44a Remove the type symbol table from ASTContext, using the scoped hash table in SemaDecl instead. We resolve a bunch of fixmes (types now give a "previous definition here" diag), remove weird mutating state from ASTContext, and allow us to have shadowed types.

5a74864a71 Add a scoped hash table for type names to SemaDecl, make Scope push it along with the value scoped hash table. 
Nothing is added to the type symtab yet though.

6a1416b3b8 Revert my last patch. Instead of having a TypeScope and ValueScope, we'll just make Scope do both!

93eea9c8bc Simplify ASTContext's transforming of NamedTypeDecls into types. It now doesn't unique them, the decls do for themselves. ASTContext still has the type symbol table.

47e034fb0e Fix element values to have a proper function type when they take an argument. Now this: 
data MaybeInt {
  None,
  Some int
}
var c = MaybeInt::Some 4;
var d = MaybeInt::Some;

-ast-dump's into:

(vardecl 'c' type='MaybeInt'
 (apply_expr type='MaybeInt'
   (declref_expr type='int -> MaybeInt' decl=Some)
   (integer_literal type='__builtin_int32_type' value=4)))
(vardecl 'd' type='int -> MaybeInt'
 (declref_expr type='int -> MaybeInt' decl=Some))

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.

4fe0a17457 Fix a problem where we didn't bind anondecls early enough which prevented them from getting their types when in nested closures. For example, 
var test : int->int->int = _0;

now sema's to:

(vardecl 'test' type='int -> int -> int'
 (closure_expr type='int -> int -> int'
   (anondecl '_0' type='int')
   (closure_expr type='int -> int'
     (declref_expr type='int' decl=_0))))
