Sema: Correctly set parent type of local types looked up in context.

When an IdentifierType is resolved to a local type in the same decl context, we weren't setting the parent type correctly, causing blowups in type checking when a local type didn't have its generic parameters from context available. Set the parent type to the DeclaredTypeInContext of the type to which we resolved an unqualified lookup. Fixes <rdar://problem/12895793>.
