Douglas Gregor 700792c4e4 Improvements and fixes for name lookup with using directives, from Piotr Rak!
Also, put Objective-C protocols into their own identifier
namespace. Otherwise, we find protocols when we don't want to in C++
(but not in C).

Douglas Gregor e254f90d94 Initial implementation of argument dependent lookup (a.k.a. ADL,
a.k.a. Koenig lookup) in C++. Most of the pieces are in place, but for
two:

  - In an unqualified call g(x), even if the name does not refer to
    anything in the current scope, we can still find functions named
    "g" based on ADL. We don't yet have this ability.
  - ADL will need updating for friend functions and templates.

Anders Carlsson a7d069d63c Use a single function for doing vararg argument promotion. Also, make sure to do the promotion before checking the type - fixes PR3340.

Douglas Gregor 6ad0ef5091 Allow Objective-C entities to be declared within a transparent context
nested in the translation unit. This fixes <rdar://problem/6476070>.

Douglas Gregor 47d3f2742a Allow downcasts of pointers to Objective-C interfaces, with a
warning. This matches GCC's behavior and addresses
<rdar://problem/6458293>.

Douglas Gregor 55ad91fecb Ultrasimplistic sketch for the parsing of C++ template-ids. This won't
become useful or correct until we (1) parse template arguments
correctly, (2) have some way to turn template-ids into types,
declarators, etc., and (3) have a real representation of templates.

Douglas Gregor a29dc05eaf Add implicit conversions for Objective-C qualified ids, e.g.,
id<P0>

The intended overloading behavior of these entities isn't entirely
clear, and GCC seems to have some strange limitations (e.g., the
inability to overload on id<P0> vs. id<P1>). We'll want to revisit
these semantics and determine just how Objective-C++ overloading
should really work.

Douglas Gregor 237f96c40f Implement implicit conversions for Objective-C specific types, e.g.,
converting a pointer to one Objective-C interface into a pointer to another
Objective-C interface, and conversions with 'id'. The semantics seems
to match GCC, although they seem somewhat ad hoc.

Fixed a few cases where we assumed the C++ definition of isObjectType,
but were getting the C definition, causing failures in trouble with
conversions to void pointers.
