Chris Lattner ad3467ee89 The -fshort-wchar option causes wchar_t to become unsigned, in addition to being
16-bits in size.  Implement this by splitting WChar into two enums, like we have
for char.  This fixes a miscompmilation of XULRunner, PR8856.

John McCall 53fa71476d Refactor how we collect attributes during parsing, and add slots for attributes
on array and function declarators.  This is pretty far from complete, and I'll
revisit it later if someone doesn't beat me to it.

Douglas Gregor da3cc0d3bf Add an AST representation for non-type template parameter
packs, e.g.,

  template<typename T, unsigned ...Dims> struct multi_array;

along with semantic analysis support for finding unexpanded non-type
template parameter packs in types, expressions, and so on.

Template instantiation involving non-type template parameter packs
probably doesn't work yet. That'll come soon.

Jeffrey Yasskin b3321531a8 Change all self assignments X=X to (void)X, so that we can turn on a
new gcc warning that complains on self-assignments and
self-initializations.  Fix one bug found by the warning, in which one
clang::OverloadCandidate constructor failed to initialize its
FunctionTemplate member.

Douglas Gregor 0192c234d5 Clean up the handling of template argument packs, especially in the
area of printing template arguments. The functionality changes here
are limited to cases of variadic templates that aren't yet enabled.

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.

John McCall aa6d98c160 Factor out most of the extra state in a FunctionProtoType into a separate
class to be passed around.  The line between argument and return types and
everything else is kindof vague, but I think it's justifiable.

John McCall 717d9b0e2f It's kindof silly that ExtQuals has an ASTContext&, and we can use that
space better.  Remove this reference.  To make that work, change some APIs
(most importantly, getDesugaredType()) to take an ASTContext& if they
need to return a QualType.  Simultaneously, diminish the need to return a
QualType by introducing some useful APIs on SplitQualType, which is
just a std::pair<const Type *, Qualifiers>.

Douglas Gregor 643526f086 Move the "volatile" bit into QualType's "fast" qualifier set,
increasing the required type alignment from 8 to 16. This provides a
2.5% speedup for -fsyntax-only on a token-cached Cocoa.h, while only
increasing memory consumption in the ASTContext by 0.8%.

Bob Wilson 7795480992 ASTContext::getVectorType should preserve the vector kind for canonical types.
This is needed for Neon types when it is most natural to define them in terms
of a typedef.  For example, Neon poly8_t is a typedef for "signed char", and
we want to define polynomial vectors as vectors of that typedef.  Without this
change, the result will be a generic GCC-style vector.  I think this is safe
for other vector types as well, but I would appreciate a review of this.

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.

Charles Davis 99202b358f Use the right calling convention when mangling names in the Microsoft C++

they technically still have the __cdecl CC).

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.

Douglas Gregor 3ade5704fe When canonicalizing nested-name-specifiers involving dependent names

Douglas Gregor f86c939bff When de-serializing a type that is supposed to be canonical, call
getCanonicalType() to make sure that the type we got back is actually
canonical. This is the case for most types, which always build a
canonical type when given canonical components. However, some types that
involve expressions in their canonicalization (e.g., array types with
dependent sizes) don't always build canonical types from canonical
components, because there is no such thing as a "canonical"
expression. Therefore, we do this extra mapping to ensure that the
canonical types we store are actually canonical.

Argyrios Kyrtzidis 65ad5691fd Put the mechanism in place to track modifications in an AST entity that were committed after
its initial creation/deserialization and store the changes in a chained PCH.

The idea is that the AST entities call methods on the ASTMutationListener to give notifications
of changes; the PCHWriter implements the ASTMutationListener interface and stores the incremental changes
of the updated entity. WIP

John McCall 942687084f __attribute__((aligned(n))) directly specifies the alignment of a declaration
unless it's a non-packed field, in which case it can only increase the

(because it's ill-formed for [[align]] to decrease alignment ever).
