Douglas Gregor db9d664244 Rvalue references for *this:
- Add ref-qualifiers to the type system; they are part of the
  canonical type. Print & profile ref-qualifiers
  - Translate the ref-qualifier from the Declarator chunk for
    functions to the function type. 
  - Diagnose mis-uses of ref-qualifiers w.r.t. static member
  functions, free functions, constructors, destructors, etc.
  - Add serialization and deserialization of ref-qualifiers.

Peter Collingbourne ab8bc06373 Generalise support for non-inheritable attributes
Inheritable attributes on declarations may be inherited by any later
redeclaration at merge time.  By contrast, a non-inheritable attribute
will not be inherited by later redeclarations.  Non-inheritable
attributes may be semantically analysed early, allowing them to
influence the redeclaration/overloading process.

Before this change, the "overloadable" attribute received special
handling to be treated as non-inheritable, while all other attributes
were treated as inheritable.  This patch generalises the concept,
while removing a FIXME.  Some CUDA location attributes are also marked
as non-inheritable in order to support special overloading semantics
(to be introduced in a later patch).

The patch introduces a new Attr subclass, InheritableAttr, from
which all inheritable attributes derive.  Non-inheritable attributes
simply derive from Attr.

N.B. I did not review every attribute to determine whether it should
be marked non-inheritable.  This can be done later on an incremental
basis, as this change does not affect default functionality.

Douglas Gregor 5590be0491 Introduce a new kind of TemplateName that captures a substituted
template template parameter pack that cannot be fully expanded because
its enclosing pack expansion could not be expanded. This form of
TemplateName plays the same role as SubstTemplateTypeParmPackType and
SubstNonTypeTemplateParmPackExpr do for template type parameter packs
and non-type template parameter packs, respectively.

We should now handle these multi-level pack expansion substitutions
anywhere. The largest remaining gap in our variadic-templates support
is that we cannot cope with non-type template parameter packs whose
type is a pack expansion.

Douglas Gregor 0dca5fdb4e Keep track of the number of expansions to be produced from a type pack
expansion, when it is known due to the substitution of an out
parameter pack. This allows us to properly handle substitution into
pack expansions that involve multiple parameter packs at different
template parameter levels, even when this substitution happens one
level at a time (as with partial specializations of member class
templates and the signatures of member function templates).

Note that the diagnostic we provide when there is an arity mismatch
between an outer parameter pack and an inner parameter pack in this
case isn't as clear as the normal diagnostic for an arity
mismatch. However, this doesn't matter because these cases are very,
very rare and (even then) only typically occur in a SFINAE context.

The other kinds of pack expansions (expression, template, etc.) still
need to support optional tracking of the number of expansions, and we
need the moral equivalent of SubstTemplateTypeParmPackType for
substituted argument packs of template template and non-type template
parameters.

Douglas Gregor ada4b79947 Start implementing support for substitution into pack expansions that
involve template parameter packs at multiple template levels that
occur within the signatures members of class templates (and partial
specializations thereof). This is a work-in-progress that is deficient
in several ways, notably:
  - It only works for template type parameter packs, but we need to
  also support non-type template parameter packs and template template
  parameter packs.
  - It doesn't keep track of the lengths of the substituted argument
  packs in the expansion, so it can't properly diagnose length
  mismatches.

However, this is a concrete step in the right direction.

John McCall 8190451ddc Introduce an AttributedType, but don't actually use it anywhere yet.
The initial TreeTransform is a cop-out, but it's more-or-less equivalent

eventually stop doing in favor of using this type.

Douglas Gregor e4ff4b56fe Replace the representation of template template argument pack
expansions with something that is easier to use correctly: a new
template argment kind, rather than a bit on an existing kind. Update
all of the switch statements that deal with template arguments, fixing
a few latent bugs in the process. I"m happy with this representation,
now.

And, oh look! Template instantiation and deduction work for template
template argument pack expansions.

Douglas Gregor eb29d18e5d Add semantic analysis for the creation of and an AST representation
for template template argument pack expansions. This allows fun such
as: 

  template<template<class> class ...> struct apply_impl { /*...*/ };
  template<template<class> class ...Metafunctions> struct apply {
    typedef typename apply_impl<Metafunctions...>::type type;
  };

However, neither template argument deduction nor template
instantiation is implemented for template template argument packs, so
this functionality isn't useful yet.

I'll probably replace the encoding of template template
argument pack expansions in TemplateArgument so that it's harder to
accidentally forget about the expansion. However, this is a step in
the right general direction.

Ted Kremenek 1d56c9eed7 Add -fobjc-default-synthesized-properties flag
to allow us to explicitly control whether or
not Objective-C properties are default synthesized.
Currently this feature only works when using
the -fobjc-non-fragile-abi2 flag (so there is
no functionality change), but we can now turn
off this feature without turning off all the features
coupled with -fobjc-non-fragile-abi2.

Douglas Gregor d2fa766ad0 Introduce a new type, PackExpansionType, to capture types that are
pack expansions, e.g. given

  template<typename... Types> struct tuple;

  template<typename... Types>
  struct tuple_of_refs {
    typedef tuple<Types&...> types;
  };

the type of the "types" typedef is a PackExpansionType whose pattern
is Types&. 

This commit introduces support for creating pack expansions for
template type arguments, as above, but not for any other kind of pack
expansion, nor for any form of instantiation.

Argyrios Kyrtzidis 1cb0de1d4c Fix diagnostic pragmas.
Diagnostic pragmas are broken because we don't keep track of the diagnostic state changes and we only check the current/latest state.
Problems manifest if a diagnostic is emitted for a source line that has different diagnostic state than the current state; this can affect
a lot of places, like C++ inline methods, template instantiations, the lexer, etc.

Fix the issue by having the Diagnostic object keep track of the source location of the pragmas so that it is able to know what is the diagnostic state at any given source location.

Fixes rdar://8365684.

Bob Wilson aeb56444f9 Add a variant of GCC-style vector types for ARM NEON.
NEON vector types need to be mangled in a special way to comply with ARM's ABI,
similar to some of the AltiVec-specific vector types.  This patch is mostly
just renaming a bunch of "AltiVecSpecific" things, since they will no longer
be specific to AltiVec.  Besides that, it just adds the new "NeonVector" enum.

Douglas Gregor 1ccc8416a0 Remove broken support for variadic templates, along with the various
abstractions (e.g., TemplateArgumentListBuilder) that were designed to
support variadic templates. Only a few remnants of variadic templates
remain, in the parser (parsing template type parameter packs), AST
(template type parameter pack bits and TemplateArgument::Pack), and
Sema; these are expected to be used in a future implementation of
variadic templates.

But don't get too excited about that happening now.

of changes; the PCHWriter implements the ASTMutationListener interface and stores the incremental changes
of the updated entity. WIP
