Argyrios Kyrtzidis 7451d1cd00 [ARC] When casting from a pointer to an objective-c object with known ownership, if the
cast type has no ownership specified, implicitly "transfer" the ownership of the cast'ed type
to the cast type:

id x;
static_cast<NSString**>(&x); // Casting as (__strong NSString**).

This currently only works for C++ named casts, C casts to follow.

Douglas Gregor 84265a09d6 When an explicit specialization has a storage specifier, error if that
storage specifier is different from the storage specifier on the
template. If that storage specifier is the same, then we only warn.

Thanks to John for the prodding.

Douglas Gregor c976f01d3f Downgrade the error complaining about presence of a storage class
specifier on an explicit specialization to a warning, since neither
EDG nor GCC diagnose this code as ill-formed.

Douglas Gregor a912197fff Downgrade the error about re-opening an inline namespace as non-inline
to a warning, since apparently libstdc++'s debug mode does this (and
we can recover safely). Add a Fix-It to insert the "inline", just for kicks.

Douglas Gregor 8b02cd0bea Extend Sema::ClassifyName() to support C++, ironing out a few issues
in the classification of template names and using declarations. We now
properly typo-correct the leading identifiers in statements to types,
templates, values, etc. As an added bonus, this reduces the number of
lookups required for disambiguation.

Douglas Gregor db44611f2e Support explicit template specialization and instantiation for members
of a C++0x inline namespace within enclosing namespaces, as noted in
C++0x [namespace.def]p8.

Fixes <rdar://problem/9006349>, a libc++ failure where Clang was
rejected an explicit specialization of std::swap (since libc++ puts it
into an inline, versioned namespace std::__1).

Richard Smith 59006e4338 Fix a few auto-related issues:
* 'auto' was being rejected on abstract-declarators with trailing return
types and on typedefs with trailing return types. 'auto' is always
allowed in these cases. This was found while testing the fix for PR 9278.

 * A very poor diagnostic was being issued for auto (f() -> int): "return
type must be 'auto', not 'auto'". This is closely related to PR 9060.

 * Trailing return type handling was happening slightly too late,
resulting in the checks for functions returning arrays and functions
returning functions being missed.

Richard Smith 27e39b11b1 C++0x's deduced auto is illegal in typedefs.
This actually rules out too much, since it also catches typedefs for pointers to functions with trailing return types:

  typedef auto (*F)() -> int;

Fix for that (and the same issue in all abstract-declarators) to follow shortly.

Douglas Gregor 13e6587313 If name lookup finds different type declarations in different scopes
that actually refer to the same underlying type, it is not an
ambiguity; add uniquing support based on the canonical type of type
declarations. Fixes <rdar://problem/8296180>.

Douglas Gregor 836a7e8468 Improve our handling of user-defined conversions when computing
implicit conversion sequences. In particular, model the "standard
conversion" from a class to its own type (or a base type) directly as
a standard conversion in the normal path *without* trying to determine
if there is a valid copy constructor. This appears to match the intent
of C++ [over.best.ics]p6 and more closely matches GCC and EDG.

As part of this, model non-lvalue reference initialization via
user-defined conversion in overloading the same way we handle it in
InitializationSequence, separating the "general user-defined
conversion" and "conversion to compatible class type" cases.

The churn in the overload-call-copycon.cpp test case is because the
test case was originally wrong; it assumed that we should do more
checking for copy constructors that we actually should, which affected
overload resolution.

Fixes PR7055. Bootstrapped okay.

Douglas Gregor 1d9ef840fa A using declaration can redeclare a typedef to the same type. These
typedefs won't have the same canonical declaration (since they are
distinct), so we need to check for this case specifically. Fixes

John McCall e9cccd86da Fix a point of semantics with using declaration hiding: method templates
introduced by using decls are hidden even if their template parameter lists
or return types differ from the "overriding" declaration.

Propagate using shadow declarations around more effectively when looking up
template-ids.  Reperform lookup for template-ids in member expressions so that
access control is properly set up.

Fix some number of latent bugs involving template-ids with totally invalid
base types.  You can only actually get these with a scope specifier, since
otherwise the template-id won't parse as a template-id.

Fixes PR7384.

Douglas Gregor 4f4946aaaa Whenever we complain about a failed initialization of a function or
method parameter, provide a note pointing at the parameter itself so
the user does not have to manually look for the function/method being
called and match up parameters to arguments. For example, we now get:

t.c:4:5: warning: incompatible pointer types passing 'long *' to
parameter of
      type 'int *' [-pedantic]
  f(long_ptr);
